Bug 267359

Application: digikam (1.4.0)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-27-generic i686
Distribution: Ubuntu 10.10

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

When I want to unmount external hdd drive I have a message that process is still running (the program window was closed long time ago) so it cannot be unmounted. However when I want to unmount another partition of the drive it goes well but I have this error.

- Custom settings of the application:
It is nonstadard. I use it in GNOME.

The crash can be reproduced every time.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
