Bug 264719

Application: amarok (2.4.0)
KDE Platform Version: 4.6.00 (4.6.0) (Compiled from sources)
Qt Version: 4.7.1
Operating System: Linux 2.6.37-gentoo-nuks x86_64
Distribution: "Gentoo Base System release 2.0.1-r1"

-- Information about the crash:
- What I was doing when the application crashed:
Amarok 2.4.0 on KDE SC 4.6.0.
When I start amarok it shows up in tray. Crashes instantly when I leftclick that icon to bring the main window up, but if I first start playback (via keyboard or rightclick context menu) then leftclick it in tray, everything's fine.

Steps to reproduce:
Start Amarok
Leftlick tray icon

The crash can be reproduced every time.

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