Application: amarok (2.4.0)
KDE Platform Version: 4.5.3 (KDE 4.5.3)
Qt Version: 4.7.0
Operating System: Linux 2.6.31-11-rt x86_64
Distribution: Ubuntu 10.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Listening to a playlist of a dozen or so MP3s. Amarok crashes randomly at any given time on any given MP3 in the playlist. It never crashes at the same time on the same file.

The crash can be reproduced every time.

-- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault
