Bug 329222

Application: k3b (2.0.2)
KDE Platform Version: 4.11.3
Qt Version: 4.8.4
Operating System: Linux 3.11.0-12-generic x86_64
Distribution: Linux Mint 16 Petra

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

I was wanting to burn some .deb and .txt, so on the file chooser I clicked on the .deb file like i do with .iso files, which show the .iso gui. But clicking on the .deb file crashed k3b. I tryed it on .txt and other .deb files but same results. music, video, and iso files work fine.

The work around is to click on "New Data Project" first, THEN choose your file in the file chooser and K3B doesn't crash.

The crash can be reproduced every time.

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