Description Alvin 2010-08-26 11:05:49 UTC

Application: amarok (2.3.1.90)
KDE Platform Version: 4.5.00 (KDE 4.5.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.32-24-generic x86_64
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Amarok package: 2:2.3.1.90-0ubuntu1~ppa1~lucid1 (Kubuntu 10.04.1)
I pressed "next track" <Meta+B>
This happens rarely.

The crash can be reproduced some of the time.

-- Backtrace:

Comment 1 Myriam Schweingruber 2010-08-26 11:23:26 UTC

The crash is caused by a 3rd-party script, please remove those selectively in the $HOME/.kde/share/config/amarokrc file and report it to the script author in http://kde-apps.org

*** This bug has been marked as a duplicate of bug 219441 ***

Comment 2 Myriam Schweingruber 2010-08-26 11:58:47 UTC

Hm, if you don't have an external script then it is a different problem. I assumed a script problem because the crash handler shos some javascript oddities.
Please install the following packages and try again:

amarok-dbg, phonon-dbg, kdelibs5-dbg, libqt4-dbg and  libglib2.0-0-dbg

Comment 3 Myriam Schweingruber 2010-08-26 11:59:12 UTC

Setting status correctly.

Comment 4 Alvin 2010-08-26 12:12:45 UTC

Packages installed. I'll report back when Amarok crashes again.

Comment 5 Myriam Schweingruber 2010-09-30 00:43:35 UTC

Any news on this? Amarok 2.3.2 has been released in the meantime. If you can't reproduce this anymore, please close the report.

Comment 6 Myriam Schweingruber 2010-10-31 16:26:12 UTC

Closing for lack of feedback. Feel free to reopen if you can reproduce this crash with Amarok 2.3.2 or later and can provide a valid backtrace.

Comment 7 Alvin 2011-05-24 11:09:34 UTC

Crash can still be reproduced in Amarok 2.4.1. Sometimes this leads to bug #258706.

Comment 8 Myriam Schweingruber 2011-05-26 08:35:44 UTC

Alvin, your feedback comes very late. Did you remove the amarok config files located in $HOME/.kde/share/config/ and try again?

Comment 9 Myriam Schweingruber 2011-05-26 08:36:50 UTC

Also, since there have been a lot of changes in the codebase since your original report, please provide a new backtrace.

New crash information added by DrKonqi

amarok (2.4.1) on KDE Platform 4.6.3 (4.6.3) using Qt 4.7.2

- What I was doing when the application crashed:

(I'm not 100% sure this is the same issue, but it occured when pressing 'next'. The difference is that the Crash Reporting Assistant appeared.)
All settings were erased to reproduce this.

After a few times of pressing 'next', Amarok hangs. The OCD is still visible at this point. Crash Assistant is not appearing.

Comment 13 Myriam Schweingruber 2011-05-29 07:55:11 UTC

Strangely enough, the backtrace indicates a problem with a 3-rd-party script, but as explained on IRC, the author has a fresh install with no additional scripts installed.

Alvin, could you please install the amarok-dbg package and provide a better backtrace?

New crash information added by DrKonqi

amarok (2.4.1) on KDE Platform 4.6.2 (4.6.2) using Qt 4.7.2

- What I was doing when the application crashed:

Amarok was playing minimised to systray with a very large playlist and crashed (like just exited with no further consequences) when I pressed global hotkey for next track. The hotkeys were all default, I haven't modified them in any way.

-- Backtrace (Reduced):

Indeed, there are no 3th party scripts installed. The provided backtrace was 
made while amarok-dbg was installed.

$ aptitude show amarok-dbg
Package: amarok-dbg                      
New: yes

Automatically installed: no

Comment 16 Alvin 2011-08-09 12:37:58 UTC

Amarok was just updated to 2.4.3 in the kubuntu-backports PPA. It still crashes regularly. (even on a fresh install)

Comment 17 Myriam Schweingruber 2011-08-09 21:34:49 UTC

Alvin, could you please provide a new backtrace as requested in comment #13?

I can try, but what is wrong with the backtrace?

Well, you didn't have amarok debugging symbols installed, so it is impossible to know where in Amarok the problem happens, see also this:

#28 0x00007f3840ca696b in ?? () from /usr/lib/libamaroklib.so.1

Yes, I did. At least when I send the last output.
I reinstalled Kubuntu (not for this bug) and installed amarok-dbg. Here are 
the last 100 lines before the crash. (Note that apport, drkonqi or whatever 
watches crashes does not notice a thing. I have the OSD active, and it just 
shows the OSD, but Amarok freezes and can't even be killed properly.)

I didn't forget the attachment. Maybe bugzilla doesn't accept mail attachments? Now uploading through the web interface.

I see. Well, I followed this guide instead:

Your last attachment seems to indicate a problem with the phonon-backend-gstreamer, but it has no debugging symbols either. Please install those and try to reproduce the backtrace again.
