Application: amarok (2.4.0)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic i686
Distribution: Ubuntu 11.04

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

I installed Amarok on Ubuntu 11.04 (with Unity Desktop) on my Samsung Q35 (Intel Core2Duo T7400, 945GM, 2,5GB RAM) Notebook. After the Installation I tried to search for a song in the Jamendo database - Amarok crashed. I tried to start it by going to its location in the database - Amarok crashed again.

The crash can be reproduced every time.

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