Sentry Crash Report:

Description loeffler.florian 2014-02-03 23:10:40 UTC 
I keep getting segmentation fault crashes when a track has finished playing and the next one is supposed to start. This doesn't happen on every track change but several times an hour. I have not noticed a single factor that triggers these crashes.

Backtrace:

Application: Amarok (amarok), signal: Segmentation fault

Reproducible: Sometimes

Steps to Reproduce:
1. start Amarok
2. load a playlist
3. start playing
Actual Results:  
amarok crashes with segmentation fault

Expected Results:  
it should have played the next song
Comment 1 Myriam Schweingruber 2014-02-04 00:32:55 UTC 
The crash is in gstreamer, not in Amarok. 

FWIW: please do not send any crash reports if you have not previously recompiled the relevant packages and their dependency libraries with debugging enabled, see also http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports#Arch
