Bug 277724

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 x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed: right click on the amarok icon in the tray.

- Unusual behavior I noticed: Before I went to close the Amarok app, its CPU usage went up to a 100% percent with no music loaded into Amarok at all. Neither there was a song playing.

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