npviewer.bin crashed with SIGSEGV in pthread_mutex_lock()

[progster]

Binary package hint: nspluginwrapper

npviewer is crashing at startup, this just began happening after the latest update on 2/15/2008. I am running amd64 on a hp pavilion 8000. I am able to reproduce it at each and every bootup. If you would like any other info please let me know.

Hi
I have the same problem and I have tried to report it. Please look here https://bugs.launchpad.net/ubuntu/+source/firefox-3.0/+bug/238150
I have followed the instruction and i'm here now.

I get the same on my amd64 with nonfree flash player, -- was just about to file the bug (well Apport was) but I see they've got 10.000 duplicates. So maybe not ;-)

Nonfree flash sucks.

Hi Guys, I solved all my problems by buying an iMac. I really would
recommend it.

As if that would solve the problem of having a closed source Flash. No way. Going to proprietary software is not a solution, it *is* the problem. I only use my Mac G5 for video editing, Ubuntu does everything else better. You (and now we) are way off topic. Hope this'll be deleted.

[jim (emile-maeyens)]

This last answer is really a bug, it wont solve the problems at all.
With Ubuntu it will be solved, it need time and at least we have the
help of many of all people in the world with a marvellous comunity.

After reading KAA's posting above, I clicked on the link there and received the following response :

«Sorry, you don't have permission to access this page. »

Intriguing ! What's so secret on that page that my accessing it is not permitted ? And why is the link publicly exposed in this manner, if readers here are not supposed to do so ?...

[nudepenguin (clintbrothers)]

The nspluginwrapper has been a pain since 8.10 alpha2, I sure hope this is fixed before the 30th! It crashes all the time. Adobe needs to get 64bit flash out so ns and 32libs are not needed.

[M Henri Day (mhenriday)]

Agree with nudepenguin about the need for a 64-bit flashplayer. But is Adobe listnening ?...

[Kevin (kevinshlee)]

I'm not sure why the status of this bug report is invalid because it is still happening. Well, it does not crash anymore when starting up as described in the main post yet does crash sometimes when surfing the web with Firefox.

[Peter Leonard (pete-peteleonard)]

Seconding - it's happened to me twice in the last 30 minutes under Ibex Beta - and I only installed flashplugin-nonfree 45 minutes ago.

Thinkpad T400, x86_64.

[Harrison Conlin (harrisony)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please answer these questions:

* Is this reproducible?
* If so, what specific steps should we take to recreate this bug?

This will help us to find and resolve the problem.

[caj411 (cajones)]

I have no idea, but I have not had it occur lately, i had forgotten
about it. One of those things.

[Peter Leonard (pete-peteleonard)]

This still happens very regularly. Flash apps will work for a period of time, and then at some point cross a threshold, at which point they will crash & continue to crash until firefox is fully restarted. The unreliability is terrible - it's a major impediment to Ubuntu being a reliable desktop replacement (it sucks, but flash usage is a major part of any web-enabled session these days).

I cannot find a reliable trigger for the bug, but a theme seems to be embedded videos from Youtube or Break.com.

[Harrison Conlin (harrisony)]

Thanks for your comments Peter,

Would the more comfortable ubuntu users please do the following (trying something a little different here)
1) edit /etc/default/apport and change to enabled=1 and then run /etc/init.d/apport restart
2) Follow steps 1-3 on https://wiki.ubuntu.com/DebuggingProgramCrash
3) sudo apt-get install nspluginwrapper-dbgsym
4) do what you usually do until flash crashes and upload the apport crash (ignore the bit about "Is the bug you’re reporting one of these? "
5) subscribe harrisony (myself)

Thanks in advance!
(note your system may become slightly slower with apport running, feel free after you get a crash and uploaded to disable apport. To turn apport off, repeat step one but change it to enabled=0)

[Tchalvak (tchalvak)]

Debugger installed, so I'll upload when I get a crash.

[Evan Charlton (evan-evancharlton)]

I installed the debugger and enabled it as per Harrison's instructions, but was never able to duplicate a crash.

I did, however, upgrade to the new Flash 10 beta (alpha? I can't remember) shortly after that and have been problem-free ever since. Not a solution, but thought I'd mention it.

[Tchalvak (tchalvak)]

I've been using Flash 10 since the moment it became available, which I think was even before Intrepid, so I don't think that this problem is solved simply by 10 (I'm using flashplugin-nonfree: 10.0.15.3ubuntu1~intrepid1 and nspluginwrapper: 1.1.2-0ubuntu1 and the problem has occurred more than once for me in that time). Now I'm waiting for it to occur again with the debug symbols package installed to lend more details to this bug, so I'd like to keep it open a bit longer.

[Tchalvak (tchalvak)]

Ok, got one that happened after the nspluginwrapper-dbgsym (sp?) package was installed, it's a new bug here:
https://bugs.launchpad.net/ubuntu/+source/nspluginwrapper/+bug/318343

Lemme know if I should mark it as a duplicate of ths one or the like.

[Dantroline (daniel-arasweb)]

I have been getting a bug with this description randomly, but at least once a reboot for the past few weeks. Especially when clicking on a crash-report notification icon, or when browsing some flash based websites, but unpredictably. Running jaunty.

[tazd (tazd-97)]

Have installed Jaunty on a new HP G70-212EM and keep getting this bug every time i boot the system.

[brentpieczynski (brentpieczynski)]

I started to watch You-Tube while using KDE and this difficulty did appear.

[Peter Leonard (pete-peteleonard)]

Very annoying - this was fixed & flash was working great in Ubuntu 8.10. I just upgraded to Ubuntu 9.04, and I'm seeing the error all over again. Why was the fix not propagated to 9.04?

[Simon Ruggier (simon80)]

What fix are you referring to? It was messed up for me in 8.10 as well.

[Jeremy Visser (jeremy-visser)]

This bug report is clearly too vague to determine what the actual problem is. It seems that this error is triggered by a range of causes, and is indicative of the symptom only, not the problem.

I am marking this bug as "Incomplete" to reflect this, as it does not aid in fixing the bug in any way.

Dear Peter,

I'm now running an amd64 kernel with the latest beta from Adobe, and it runs
just fine. I suggest eveyone running the 64bits wrapper to change ASAP to
the new ".so" beta. It was already been discussed "ad nauseaum" in launchpad
threads about flash plugin wrapper.

[brentpieczynski (brentpieczynski)]

I seam to keep finding ways to crash that, npviewer.bin so when I finish filing a group of bug reports, it's off to the Internet. These are often the result of my switching to KDE for assistance with regaining support with my sound, for those Internet-videos.

[brentpieczynski (brentpieczynski)]

This is one of my favorite items to crash, with the use of Kubuntu to run that KDE, this might be the result of some hidden difficulty, with the system.

[brentpieczynski (brentpieczynski)]

Happy-Crash-Time everyone, did my filing of a bug-report, cause the program to crash?

[Peter Leonard (pete-peteleonard)]

So I think I've got things working again.

What I did:

Remove flash using apt-get:

  $ sudo apt-get remove flashplugin-* --purge

Remove flash manually:

  $ locate libflash\*
  $ rm <examples of libflashplayer.so>

Download most recent version of flash from adobe, unpack, and install in ~/.mozilla/plugins

So far, problem solved. Version off the adobe website was 10.0.22.87:

[Matthew Murphy (chthonical)]

Karmic. Same crash bug popping up. Threw in a report.

[Simon Ruggier (simon80)]

The 64-bit version of flash is stable, and it appears to be getting
released alongside updates to the 32-bit versions, so I really don't
see why Ubuntu still insists on provides 64-bit Ubuntu users with the
32-bit plugin and nspluginwrapper, which has been broken for at least
the last 3 releases of Ubuntu. It would be pretty ridiculous if this
bug were still in Karmic, and it's this sort of minor but conspicuous
snag that stigmatises 64-bit operating systems for desktop users.

[Georg (georg-lippold)]

I must also second Peter's #37 comment and Simon's #44 comment. After following the instructions in #37, flash works fine for me. The download page with the most current 64bit flash plugin is here:

I also had a lot of trouble with flash under Ubuntu amd64.
I used the flashplugin-nonfree packages etc.

Now participating 9.10 beta tests I decided to give adobes 64bit beta version a try - it runs like a champ.

No interferences with sound, no crashes anymore, it simply does its job.

Try go for Its a pre-release already:

http://labs.adobe.com/downloads/flashplayer10.html
and put the so file in the proper directory.

You must uninstal any former installed flash plugins otherwise it wont work.

Thanks for your bug report. Please try to obtain a backtrace http://wiki.ubuntu.com/DebuggingProgramCrash and attach the file to the bug report. This will greatly help us in tracking down your problem.

[Georg (georg-lippold)]

I recommend installing the Flash-Aid Firefox plugin. Since I use it, I always get the most up-to-date version for 64bit, and it is installed and updated automatically. The plugin is available for download here:

https://addons.mozilla.org/en-us/firefox/addon/flash-aid/

I would recommend that the Ubuntu packaging team finds out how Flash-Aid manages to install Flash without any problems and then changes the nspluginwrapper package so that it does the same things that Flash-Aid do. Alternatively, the nspluginwrapper package could install the Flash-Aid plugin by default and let the user do the Flash maintenance via the plugin - that will at least allow most users to use Flash.
