Application: amarok (2.5.0)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-25-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I close Ubuntu 12.04 amd64 and it crash before finished shutdown. Doesn't mater if Amarok is open or close, if amarok were open at least once during the session, then Ubuntu crash at shutdown.

The crash can be reproduced some of the time.

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