[natty] easymp3gain crashed with SIGSEGV

3)
I expect to add files to easymp3gain list

4)
This happens while adding folders recursively, and may, or may not occur on exactly the same set of files. If I try to add same set of files several times, then some of attempts succeeds. This error occurs ~50% of attempts.
I was only able to trigger Apport by using Drag and Drop method to add folders to easymp3gain. Otherwise, when using "File">"Add folders recursively" command of easymp3gain, I only got error window as in attachment.
If you need more info let me know.
I was wondering if this bug might be related to #610928 , but If that was true, than none of my attempts would succeed, wouldn't it?
Cheers, Patryk.

Hi! First of all: Thank you for this excellent bug report! This is exactly how it should be :)
So, regarding your bug, it is related to http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=597260 , unfortunately this can't be fixed in Natty. (but it has already been fixed in Oneiric)

> I was wondering if this bug might be related to #610928 , but If that was true, than none of my attempts would succeed, wouldn't it?
You can't do anything with the Ubuntu packages, but you can easily try the Debian package. Just install "easymp3gain-gtk" manually from Debian ( http://packages.debian.org/sid/easymp3gain-gtk ), this should fix your problem. (If not, let me know)
Regards
   Matthias

No problem, and thanks for appreciation.

I have installed:
patben@esp-patben-lin:~$ apt-cache policy easymp3gain*
easymp3gain-gtk:
  Zainstalowana: 0.5.0-6
  Kandydująca: 0.5.0-6

Unfortunately the problem still occurs. I think I was able to find one
3MB mp3 song, which generates error at each attempt. I can attach it, if
it is not against any rules here?

Okay, reopening this bug.
You can send me the file, if you think it causes the error (attaching it is not a good idea): <email address hidden>
Please install the package "easymp3gain-gtk" and "easymp3gain-dbg" from my Testing PPA ( https://edge.launchpad.net/~ximion/+archive/tests/+packages , compiled for Oneiric but can be used with Natty too, you need to downgrade the Debian packages). Then run easyMp3Gain in GDB:
1) Install GDB
2) Type "gdb --args easymp3gain" in a terminal
3) Type "run" and enter
4) Let easymp3gain crash
5) Return to terminal and type "bt full"
6) Show all log messages
7) Type "q", enter
8) Attach the complete terminal log here :)

Thank you for your report!

However, processing it in order to get sufficient information for the
developers failed (it does not generate an useful symbolic stack trace). This
might be caused by some outdated packages which were installed on your system

Already sent. I have noticed it is in fact an OGG not an MP3, but anyway
if program gets wrong file - it should report a message - not an SIGSEV.

I'll do it as soon as build will succeed. Currently there is "Dependency

Oh sorry.... The package should be ready now (in a few minutes).
Did you install vorbisgain?
btw: Looks like Apport is running amok...

[Patryk "LeadMan" Benderz (leadman)]

Hi again, first of all - sorry it took so long to respond.

> Oh sorry.... The package should be ready now (in a few minutes).
I have just installed, the package you have provided, but I was not able
to reproduce the bug with this version.

> Did you install vorbisgain?
yes.

> btw: Looks like Apport is running amok...
I don't grasp this... what is 'amok'?

Regarding that I was not able to reproduce this bug, I have un-installed
easymp3gain 0.5.0-6~o5 and installed stock 0.5.0-4. Unfortunately there
was no dbg package in repository, but i have run it in gdb and here is
terminal output:

Quit anyway? (y or n) y

So I suppose this doesn't help you out much, as there was no debug
symbols? Anything more I can do to help?

Hmm, weird... The backtrace is not very useful without debug symbols installed.
I guess this error is related to an LCL <> GTK2 incompatibility, which has been fixed with rev6 of this package / a new upload of the Lazarus package.
We will have this fixed in Oneiric :-)
(You maybe can combine the rev6 debug package with the rev5 package btw.)

normal install failed, cause easymp3gain-dbg depends on easymp3gain-gtk
(= 0.5.0-6~o5);
Hovewer using dpkg --force-depends-version allowed me to install rev6
dbg symbols. I have used this wiki to make back trace this time:
https://wiki.ubuntu.com/Backtrace I hope it will be more useful at this
attempt, however dbg symbols were not found again. Details in
attachment.

CRC mismatch - okay, it was worth a try...
I suggest you use the PPA packages and try this again when Oneiric is released. There are lots of changes made in Lazarus, so this issue might have been fixed already in newer Ubuntu and Debian versions.

I don't give up easily...
after googling for a while I found:
https://wiki.ubuntu.com/Kernel/Reference/ACPIDebuggingAMLwithSystemTap
making similar steps as described there, I have added debugging symbols
repository to my OS. (steps 2.1 and 2.2) This allowed me to install
debugging symbols for rev4:

root@esp-patben-lin:/etc/apt/sources.list.d# apt-cache policy easymp3gain*
easymp3gain-gtk:
  Zainstalowana: (brak)
  Kandydująca: 0.5.0-4

  Kandydująca: 0.5.0-4
  Tabela wersji:

        500 http://ddebs.ubuntu.com/ natty/universe amd64 Packages

I have made two debug runs. At first I got SIGSEGV right after program
started, thus I was not able to add any mp3 files. At second attempt
program started normally, and I go SIGSEGV after drag&drop folder with
mp3 files. Terminal gdb dump from both runs attached. Now you have more
data to analyze ;P

P.S. Probably it would save a lot of your time, if you tell reporters to
use this two wikis:
1) installing debugging symbols:
https://wiki.ubuntu.com/Kernel/Reference/ACPIDebuggingAMLwithSystemTap
2)Generating backtrace:
https://wiki.ubuntu.com/Backtrace

Wow, thanks for the effort!
I didn't know about the "ACPIDebuggingAMLwithSystemTap" page, otherwise I would have pointed you to than - anyway, something good to know :)
With the additional information, I can mark this bug as duplicate, this should have been fixed with Lazarus 0.9.30 (a dependency of easyMp3Gain which provides a widgetset abstraction layer, the LCL).
This is also related to http://bugs.freepascal.org/view.php?id=16439
If you need packages for easyMp3Gain, I can provide some - fixing this in Natty will not be possible unfortunately, due to Ubuntu's policy. (I would have to add a new version of an application to a frozen repository - unfortunately, a fix for this error is not that trivial so that it could be fixed without a new-version-upload.)

I have just used points related to installing ddebs. Maybe there is more
appropriate wiki related just to ddebs, but I couldn't find it...

> If you need packages for easyMp3Gain, I can provide some
Thanks, but I'll just use ones from your repository (0.5.0-6~o5) - they
were working fine.
Thank you for quick responses with this bug - i do not experience this
very often. Cheers!
