Application: amarok (2.4.0.90)
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Launched amarok from kicker and a shell as well and both methods resulted in a crash. I had just updated akonadi from kubuntu's backports repo minutes previous to this.

- Unusual behavior I noticed:
The splash screen launched, then the app window began to draw on screen slowly the exits.
 
- Custom settings of the application:
Other than my last.fm info, possibly a couple plugins can't remember

The crash can be reproduced every time.

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