Application: amarok (2.7.0)
KDE Platform Version: 4.10.1
Qt Version: 4.8.4
Operating System: Linux 3.8.0-15-generic x86_64
Distribution: Ubuntu Raring Ringtail (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
I was listening to an album and my collection showed music from the artist. A song was selected which album I had changed before (it showed up under the old album title, though). When I clicked on 'show album in media sources' playback stopped and Amarok crashed.

-- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
