Bug 228957

Application: amarok (2.2.2.90)
KDE Platform Version: 4.4.00 (KDE 4.4.0) (Compiled from sources)
Qt Version: 4.6.2
Operating System: Linux 2.6.31-thinkpad x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
When I did a "world update" on my Gentoo today, the Amarok package was rebuilt for a reason I didn't understand. Not sure if that is related to the bug. Interestingly, no obvious dependency of Amarok was rebuilt at the same time. The only KDE packages of which new versions were installed were kde-base/kdepimlibs-4.4.0-r1 and kde-base/kdesdk-kioslaves-4.4.0.

When starting Amarok, it crashes after a few seconds (during the Splashscreen, but before showing the main window).

The crash can be reproduced every time.

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