Application: amarok (2.5.0)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic i686
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed: Nothing, I was not on my computer
Amarok plays a dozen of songs, then pauses at the end of a song. If I try to resume or switch to the next song, it crashes.
I have managed to reproduce the bug (sometimes, amarok only freezes but not crashes), and i can assure that it is not linked to a specific song.

The crash can be reproduced some of the time.

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