Sentry Crash Report:

Description Mathias Panzenböck 2012-05-13 16:15:36 UTC 
Application: amarok (2.5-GIT)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.1
Operating System: Linux 3.3.4-3.fc16.x86_64 x86_64
Distribution: "Fedora release 16 (Verne)"

-- Information about the crash:
- What I was doing when the application crashed:
A track (~1h podcast) finished playing and for some reason the next podcast did not start to play. So I double clicked the next podcast which lead amarok to crash.

After that amarok crashed several times on startup with a basically unusalbe stack trace (no information about functions or libs).

I compiled amarok from current GIT.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 1 Mathias Panzenböck 2012-05-13 16:21:53 UTC 
The crash seems to be reproducible. This is the file that crashes:
http://meta.metaebene.me/media/raumzeit/rz037-tandem-x.m4a

I really wonder how anyone can use Amarok these days. It just keeps crashing all the time.
Comment 2 Myriam Schweingruber 2012-05-14 14:41:19 UTC 
The problem is with the phonon-backend-gstreamer. I can play it without problems here with the phonon-backend-vlc.

*** This bug has been marked as a duplicate of bug 288305 ***
Comment 3 Mathias Panzenböck 2012-05-14 14:56:16 UTC 
Well, the VLC backend is no option for me, because (as I reported in another bug) it produces horrible sound errors. VLC works great. Just the VLC backend is the problem. I hope there will be a fix for either backend soon. Otherwise amarok is just unusable. I can only fondly remember the days when the Xine backend worked/was maintained. :(
Comment 4 Myriam Schweingruber 2012-05-14 15:13:23 UTC 
The phonon-backend-vlc works perfectly fine for me, I can't reproduce an of these sounds you report. 

Please make sure you report Phonon-backend related problems to Phonon, there is nothing we can do on the Amarok side. I have checked the bug reports you made and almost all are Phonon related, please make sure you report bugs at the correct place. It might be worth to talk to the Phonon developers on #kde-multimedia about your problems, it might be a setup problem of your installation or a problem with the hardware you use.
