Description darthanubis 2011-10-16 14:27:49 UTC 
Application: amarok (2.4.3)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
Amarok was idle in the taskbar, started Miro, and Amarok crashed.
- Custom settings of the application:
Daap extention enabled.

Starting Amarok with DAAP ext. disabled I cannot reproduce the bug.
http://pastebin.com/NwRvs83J

The crash can be reproduced every time.

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