Application: amarok (2.3.1)
KDE Platform Version: 4.5.00 (KDE 4.5.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.32-24-generic i686
Distribution: Ubuntu 10.04.1 LTS

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

I had just clicked on the launcher, when Amarok icon started bouncing next to the pointer as usual. However, the window didn't show up, and I received this bug report. I didn't do anything else, so I'm not sure as to how to reproduce it.

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