Application: amarok (2.4.0)
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-27-generic x86_64
Distribution: Ubuntu 10.10

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

1. Changed the listing of my music from "artist/album" to "genre/artist/album"
2. Discovered some tracks with wrong genre
3. Clicked the wrong genre entry and changed it for multiple files (e. g. from "Dance & DJ" to "Dance")
4. Amarok crashes

The crash can be reproduced every time.

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