Bug 281127

Application: amarok (2.4.3)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic x86_64
Distribution: Ubuntu 11.04

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

I swapped my harddisk to a new computer. The new computer starts fine and everything including sound works fine without the need for any adjustments (Hi Mr. Gates). 
With the first start on the new computer Amarok crashed allthough after several attempts Amarok worked. Today its the same problem.

Other players work fine.

The crash can be reproduced every time.

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