Application: amarok (2.5.0)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-15-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:

I started Amarok 2.5.0. I was able to start and use it twice, but now Amarok just crashes when trying to start, even before the main window appears.

The installed Amarok 2.5.0 was taken from the Kubuntu Backports PPA.

The crash can be reproduced every time.

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