Description Martin Harvan 2011-11-17 17:36:44 UTC 
Application: amarok (2.4.3)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.1.1-1-ARCH i686
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
I noticed this problem occurs randomly when changing song (either manually or automatically). Sometimes it happens fairly often, other times amarok plays for hours without problem.
I am using archlinux with gnome-shell, pulseaudio and gstreamer as backend.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Amarok (amarok), signal: Aborted
