Application: amarok (2.4-GIT)

Qt Version: 4.7.1
Operating System: Linux 2.6.34-12-desktop x86_64
Distribution: "openSUSE 11.3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Nothing, Amarok is configured to play random tracks from my playlist.
Amarok crashed after a track finished playing and the next one started.

Thanks.

The crash can be reproduced some of the time.
