Bug 269164

Application: amarok (2.4.0)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-30-generic x86_64
Distribution: Ubuntu 10.04.2 LTS

-- Information about the crash:
Aoarok crashed every Time Amarok scans the USB-Device (i start it in console with amarok --debug, there i see the scan-activity) and i try to stop (with the Button in amarok UI). It also crashes if I try to reboot the PC while scan the usb-hdd-drive.

The crash can be reproduced every time.

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