Bug 265301

Application: amarok (2.4-GIT)
KDE Platform Version: 4.5.3 (KDE 4.5.3)
Qt Version: 4.6.3
Operating System: Linux 2.6.32-5-amd64 x86_64
Distribution: Debian GNU/Linux 6.0 (squeeze)

-- Information about the crash:
- What I was doing when the application crashed:
I have try to eject a NTFS disk using eject icon in amarok. This disk does not contain any folder of the collection.
Just after I have tried to eject the disk from the kde device-notification and it indicates that the device is busy.

Eject on other external drive (in ext3) doesn't crash but doesn't work anyway.

The crash can be reproduced some of the time.

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