Bug 283496

Application: k3b (2.0.2)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.4
Operating System: Linux 2.6.40.4-5.fc15.i686.PAE i686
Distribution: "Fedora release 15 (Lovelock)"

-- Information about the crash:
- What I was doing when the application crashed:
I had just inserted a DVD
Fired up K3b
Clicked on the DVD in the file tree
Crash occured

- Unusual behavior I noticed:

My usual KDE4 install crashed (still to debug) so I logged in to Gnome

The crash can be reproduced every time.

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