Qt Version: 4.6.2
Operating System: Linux 2.6.32-17-generic x86_64
Distribution: Ubuntu lucid (development branch)

-- Information about the crash:
Since I have updated to Amarok 2.3, it crashes everytime when starting the application. I've tested it on Ubuntu 9.10 and 10.4 beta.

The crash can be reproduced every time.

 -- Backtrace:
