Application: amarok (2.4.3)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.3
Operating System: Linux 2.6.40.3-0.fc15.x86_64 x86_64
Distribution: "Fedora release 15 (Lovelock)"

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

Clicking any of the icons on the mounted device bar in left sidebar causes Amarok to crash. The behaviour occurs on Amazon Kindle and Huawei Ideos 8500 (android phone) flash card mounted as storage. 

Error doesn't occur with any pendrives, Nokia E71 flash card (symbian phone) and HTC Touch Pro flash card  (winmo phone).

The crash can be reproduced every time.

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