Frequent crashes when "Changing Calibres Behaviour"

[Colin Clarke]

Windows XP (32 bit)

After installing 0.8.57 the occasional crashes have become frequent. Adding an e-mail address took ~ 20 trys, crashing before I could apply the new address.

Virtually any attempt to customise crashed while trying to make the change, or very shortly after applying a change.

Windows crash accomp file attached for the last (change to multiple author parsing string).

Actions:
For this crash, I went to Tweaks and added to |; to the default string.
After pressing apply, there was a pause and then the program crashed.
The change had been applied when I restarted Calibre (it didn't achieve what I wanted though)

[Kovid Goyal (kovid)]

Go to preferences->Look & Feel and change the user interface style to
default. And/or downgrade to calibre 0.8.55. Something on your system is
incompatible with either the new style or Qt 4.8.2. Old releases of
calibre are available here:
http://sourceforge.net/projects/calibre/files/

[Colin Clarke (staffie2001uk)]

I didn't actually have quicktime installed, I was using a codec in the K-lite codec pack.

Installing the latest Quicktime appears to have solved the problem.

Thanks for the prompt response.

[Kovid Goyal (kovid)]

@kater: Did you do what I suggested above?

[kater (kater)]

Hi Kovid,
Thanks for the response!! Actually, I did not, because a) the system that the solution was referring to was XP x86 whereas mine is Win7 x64, and b) because in the reports I also got the 'Problem Event Name: BEX' and thought I might forward it to you so you know it's not only the 'Problem Event Name: APPCRASH'.
Do you still think I should apply your proposed solution?

Kind regards,
Constantin, (registered user)
Athens, Greece

P.S.
I was thinking that perhaps it would be good to have another feature (i.e. feature request). This could be at the 'Edit metadata individually' window, where, I think, a button next to the Series field (just as you have wisely put a button next to Title and Author) by which user could jump directly to editing the series.
I also think that perhaps, if possible, you could add the search function/field, at the 'Category editor', 'Manage Publishers' and 'Manage Tags' so user could directly search for a series, publisher or tag to edit, rather than scrolling.

[Kovid Goyal (kovid)]

Yes, it still applies.

[kater (kater)]

Hi Kovid,
I did it, it 'feels' more stable, but the problem re-occurred once again. I'll post details at next hang.

Just a couple of ideas Kovid.

[kater (kater)]

Hi Kovid,
In order to downgrade do I have to uninstall? The program would not let me downgrade it. Any ideas?

Thanks

[Kovid Goyal (kovid)]

Yes, you uninstall and then downgrade. Uninstalling does not affect your
books/settings.

[kater (kater)]

Thank you Kovid so much for your continuous effort and time!!

Dear Kovid,
How will I know when to update to the 'smooth' version so as to download
it? Or should I NOT update the program at all?

I asked you the late3st question because after I downgraded my Calibre,
I lost all my plug-ins and cannot download them due to compatibility issues.

You will just have to try it from time to time to see if your issue goes away.

[kater (kater)]

I see. Thank you Kovid for your kind response.
Do you, by the way, have any idea what is it that's causing the erratic
behaviour in the program?

[Kovid Goyal (kovid)]

If I am ever able to figure out the cause, there will be an entry in the changelog that will look like, "fix for x issue causing crashes". Keep an eye out for that type of entry. However, I suspect that this is caused by something below the level of calibre code (i.e. something in the libraries calibre uses for its UI in combiation with something on your system), as such it is not something that I can fix.

[kater (kater)]

If it helps, I may add that I installed QuickTime as the other used
suggested, but this did not solve the issue.
I may also add that this behaviour was like the program was "searching"
for something and froze on the way to get it. It would happen when the
program sought to write values for a book, or show values for a book.
Anyway, worry NOT, we love you and the program and we are happy as it is.
Be well man, stay safe, and be happy!!

@Constantin: See
http://www.mobileread.com/forums/showthread.php?p=2134316 it contains a
calibre build that might solve your issues.

[kater (kater)]

Dear Kovid,
Thanks for taking the trouble to make a modified version available and
ALSO for taking the time to let me know about it.
This is exactly just as I thought and believed from the first time I saw
your program: You are a man who takes pride in and loves his work.
I am and shall remain a loyal follower of you and your work and,
REGARDLESS whether this version will work or not, I shall make another
donation, just as a small token of my appreciation for your kindness,
time, effort and amazing work!
*Be well and be safe Kovid!*

[kater (kater)]

Dear Kovid,
After almost 2 days of the new, modified version you suggested, I can
safely say that the problem is less persistent, but still there,
unfortunately.
It occurs, but less frequently than before, mainly when the program is
attempting to turn search results. Hope this helps...
Don't fret, I am certain you'll figure this out, sooner or later.

Be well friend Kovid,

What do you mean by "turn search results"? You mean when you enter
something in the search box?

[kater (kater)]

Yes, exactly so Kovid.

[Kovid Goyal (kovid)]

This happens when you type something only or also when you click in the
Tag browser, or use the advanced search dialog?

[kater (kater)]

This behaviour occurs MAINLY when I copy-paste or type in the advanced
search window.
Would it help you if I tried to replicate the error and send you an avi
file?

The download took too long and got aborted. You have someplace else you

[Kovid Goyal (kovid)]

Got it, thanks. Nothing obvious jumps out at me from that video but let
me think about it a little.

[Kovid Goyal (kovid)]

Did you notice any crashes anywhere else, apart from searching? Like in
the edit metadata dialog or when editing metadata directly in the book
list?

[kater (kater)]

Yes, the edit metadata window shows the same behaviour, but with less
frequency in this build. The metadata window would cause the program to
crash after a number of books, not always standard. For example it did
it to me now, after editing 34 books, straight without any problems. On
book 35, it crashed. Funilly, it popped up a never-before seen error
window, but it was to fast and so i could not read what it said.
So, it is not as consistent to replicate the error as it is when
searching or when copy-paste to the search field.
The previous build of calibre would crash also when directly editing
metadata (e.g. copy-paste values), but I did not test it with the
current build.
  Hope this helps man,

Constantin

If there is anything I can do to help you out, please do NOT hesitate to
let me know.

[Kovid Goyal (kovid)]

One more thing that would help is if you can attach the metadata.db file
from your calibre library folder to this ticket. It might help me
reproduce the crash.

[kater (kater)]

Kovid, the metadata.db file I have is 105 mb, and cannot be sent via
email. I uploaded it to
fileconvoy and you may dl it from the following address:

I still cannot replicate the crash with your metadata.db, but I re-wrote the component that I suspect is involved from scratch (the field used to edit authors/tags/etc). Try this build and see if it resolves the issue for you:

http://calibre-ebook.com/downloads/betas/calibre-0.8.59.msi

[Lorenzo Kampel (q1-lorenzo-im)]

Dear Kovid,

   Thanks for addressing this miserable bug.

I've been experiencing the same series of program crashes since installing 8.57.
I installed the beta supplied on 07/09 and though the frequency diminished it still occurs.
I subsequently updated to 8.60 and the problem is occurring as irregularly. Along the way I also returned the User Interface Style to System Default. No change

Thanks for your continued help
Lorenzo in Berkeley, CA

[Kovid Goyal (kovid)]

Do you have any calibre plugins installed? Go to preferences->plugins and click show only user installed plugins to check. If you do, try disabling them and see if the crashes stop.

[kater (kater)]

Dear Kovid,
As said, I returned on Saturday 14/0/2012 and installed, as per your
instructions, the build you mentioned in your email. I tried it over the
weekend and I noticed fewer hangs (but they were still there,
unfortunately).
Do you think that I should install the latest build?
Perhaps disable the plugins, as you suggested to the other user?

Many and kind regards,

[Kovid Goyal (kovid)]

Yes, try disabling the plugins.

[Lorenzo Kampel (q1-lorenzo-im)]

Dear Kovid,
   This seems to be a tough one. I've disabled ALL user plug-ins; one at a time, with a program restart between each disable.

The failure is still recurring.

Regards,
Lorenzo

[Kovid Goyal (kovid)]

Just to clarify, the crash happened after you had disabled all the user plugins and restarted calibre?

[Lorenzo Kampel (q1-lorenzo-im)]

Yes, I individually removed each user plugin, restarted Calibre, continued making metadata modifications to books in the library. A crash would soon occur and I would remove the next plugin with the same results. Eventually all plugins were removed and the crashes continued to occur.

Thanks,
Lorenzo

I've been running with the Tag Browser suppressed for a while. Crashes still occur.

Try a clean windows install, that is, uninstall, delete c:\Program Files (x86)\Calibre2 and then re-install.

[kater (kater)]

Thanks Kovid for the prompt and swift response.
Is there a way to save my settings as to restore them after the clean
install?
I mean I hate to lose all the nice customisations and settings...

Doing this will not affect your settings/books.

[kater (kater)]

Dear Kovid,
I just had an idea about the reason of this problem and although it may
be stupid, I though I might as well share it with you.
Could it be that if user has a very large number of books, then the
program functions / db / cache, you name it, somehow floods and cannot
properly handle the search, display (or whatever) info and therefore it
hangs?
Again, this is just my hunch, call it a stupid idea if you like, just
though it might give you another point of view.

No, it isn;t that simple. As I said, I tried with your db on my windows

hypothesis yourself by creating a seconf small library and working with
that. It may be that if the crash is timing related, that will affect
it.

It "feels" like the program hangs when trying to read/write information...

I had one other idea, it may be that you have some other program installed on your computers that has its own copy of the Qt DLLs in a version that is incompatible with calibre's copy. If you have the path to that programs' install directory in your PATH variable, then the incorrect DLLs might be loaded. One example of such a program is MikTeX. Check the value of your PATH variable. You can do that with

echo %PATH%

in a command prompt.

[kater (kater)]

Hi Kovid,
Sorry I could not respond earlier to your mail, but I had taken my son
to his summer vacations and was away from my computer.
Since I do not have your technical expertise, could you please try to be
more specific as to the command?
Fact of the matter is that indeed I have at least 3 files with the same
name in my system, all in different sizes, used by different programs,
so this could indeed be the case.
But please do be more specific (i.e. instructions) as regards the DOS
command.

Kind and best regards,
Constantin,
Athens, Greece

You dont have to use a DOS command you can do it via the windows control panel as well, here are some instructions: http://www.java.com/en/download/help/path.xml

Basically remove any directories that contain Qt DLLs from the PATH, the restart your computer and try running calibre and see if it makes a difference.

[kater (kater)]

Dear Kovid,
The only System Variable I have is "Path" (please kindly note the
case...) and the
Variable name is "Path"
Variable values is "C:\Program Files (x86)\NVIDIA
Corporation\PhysX\Common;%CommonProgramFiles%\Microsoft Shared\Windows
Live;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program
Files (x86)\Common Files\Acronis\SnapAPI\;C:\Program Files (x86)\SDL
International\SDLX;C:\Program Files (x86)\Calibre2\;C:\Program Files
(x86)\QuickTime\QTSystem\"

So, what would you suggest i do?

Kind regards,
Constantin

Look for the file QtGui4.dll in any of the directories listed in your Path variable. If it is there in any of them, remove that directory from the Path, restart your computer and then see if the calibre crashes go away.

[kater (kater)]

Dear Kovid,
As you can see from the attached jpg file, there is a large number of
the same file in different directories, which are NOT listed in the

Variable value "Variable values is "C:\Program Files (x86)\NVIDIA
Corporation\PhysX\Common;%CommonProgramFiles%\Microsoft Shared\Windows
Live;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program
Files (x86)\Common Files\Acronis\SnapAPI\;C:\Program Files (x86)\SDL
International\SDLX;C:\Program Files (x86)\Calibre2\;C:\Program Files
(x86)\QuickTime\QTSystem\"

As you can see there is also Acronis backup and I am rather reluctant to
meddle with it since their product is *TOTALLY **_unstable _*and I would
not want to find myself having to uninstall and reinstall Acronis backup
again.
What is your suggestion?

Kind regards
Constantin

Removing entries from Path is totally reversible. If removing something causes a problem, just put it back again. At least you will find out if that is indeed the cause of your crashes or not.

[Jacob N Weiner (dafkanik)]

Tried this. Still have Calibre shutting down after only 1 or 2 entries.

Title:
 Frequent crashes when "Changing Calibres Behaviour"
Status in calibre: e-book management:
 Invalid
Bug description:
 Windows XP (32 bit)
  After installing 0.8.57 the occasional crashes have become frequent.
 Adding an e-mail address took ~ 20 trys, crashing before I could apply
 the new address.
  Virtually any attempt to customise crashed while trying to make the
 change, or very shortly after applying a change.
  Windows crash accomp file attached for the last (change to multiple
 author parsing string).
  Actions:
 For this crash, I went to Tweaks and added to |; to the default string.
 After pressing apply, there was a pause and then the program crashed.
 The change had been applied when I restarted Calibre (it didn't achieve what I
anted though)

I searched for copies of qtgui4.dll and found a second copy under Google Music manager. I renamed that module and restarted Calibre. As soon as I did an advance search, calibri displayed the results then crashed with the same error.

I am running calibre on a second computer. I checked and I have 9 copies of qtgui4.dll all different versions. I have not had the sudden failure problem on this machine.

Some users have reported that this crash was being caused for them by RoboForm an automatic form filling software that attaches itself to all programs n windows. If you are using RoboForm, either uninstall it, or add calibre to the list of excluded programs in the RoboForm settings.

[Bart Bone (b-bone-s)]

Thanks Kovid for your suggestion to put calibre on the excluded programs list of Roboform , that did the trick for my frequently crashing Calibre under Windows 7 x64 Ultimate.

I have not seen any crashes yet, i will keep my fingers crossed!

Thanks again and i hope this was the culprit.

Best regards,
Bart Bone

What were you doing when you got the crash?

[kater (kater)]

/Hi Kovid!//
//Good morning and thanks for getting back to me on this!//
//To answer your question, as a matter of fact I was just starting the
program, nothing more. And, as a result, the program would not start at
all, but keep crashing to this error. //
//Please kindly note that I have TuneUp Utilities 2013 and it has a
"Live Optimization" feature which 'deprioritizes' programs, so I
excluded Calibre and logged out. I logged on to Windows back again and
started Calibre with no problems. This may have been the reason. //
//
//I shall monitor the behaviour and get back to you if it shows again.//
//
//If it does not, and some other user experiences this problem, keep in
mind that it may be caused by the "Live Optimization" feature of TuneUp
Utilities 2013...//
//
//Best, kind and most sincere //regards,//

[kater (kater)]

Dear Kovid,
I have a large number of books and so, when I try to start Calibre it
takes a long time to start, and when it does, it consumes ~670MB of
memory. This per se is not a problem, but when I try to edit book tags,
titles, authors, etc., it really takes a very long time, although I have
still a lot (~8GB) of free memory.
If you don't mind this very much, could you please see to it too?

A happy, registered user who loves your work and admires your dedication
to us users.

Kater,

There are many things you can do to improve performance

1) Hide the Tag Browser
2) SPlit your large library into multiple smaller libraries
3) Exclude the calibre library folder and program files from anti-virus
etc.

A bit of googleing will show you many other things people do to improve
performance with very large colelctions.

[kater (kater)]

Dear Kovid,
Thanks for taking the time to answer. You are sooo kind!
I appreciate your hints and shall try to implement them!
