Application: amarok (2.6.0)
KDE Platform Version: 4.9.3
Qt Version: 4.8.3
Operating System: Linux 3.5.0-18-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:
Just starting it...
After three or four attempts of starting it, I removed (well, remamed to amarok*.old) all amarok-related files in .kde/share/apps and .kde/share/config and it started with a default configuration and blank library.

The crash can be reproduced some of the time.

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