Bug 283001

Application: k3b (2.0.2)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.36.2-2mnbcustom i686
Distribution: "Mandriva Linux 2010.2"

-- Information about the crash:
K3b crashes after deleting a folder from the file list view by pressing Shift+Delete.
I had waited several seconds for the folder to disappear. Instead K3b crashed.

The crash can be reproduced every time.

 -- Backtrace:
Application: K3b (k3b), signal: Segmentation fault
