Bug 267420

Application: amarok (2.3.2)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-25-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed: I just Opened amarok to listen an mp3. Amarok starts the first time with no gui, only the icon on toolbar. When I clicked on the icon on toolbar, Amarok crashed and it didn't open again. Always crashes.

The crash can be reproduced every time.

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