Bug 305298

Application: krusader (2.3.0-beta1 "New Horizons")
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.2
Operating System: Linux 3.2.0-3-amd64 x86_64
Distribution: Debian GNU/Linux testing (wheezy)

-- Information about the crash:
- What I was doing when the application crashed:
1. Navigate Krusader to some random .jpg file.
2. Press F3 (to open this .jpg in internal viewer).

This is happening randomly, it can either open file or crash.

- Additional info:
I'm viewing files mainly through Gwenview, and call stack reported forced me to install debug packages for libgwenview to "be useful", so maybe it's some kind of integration problem between Krusader and Gwenview.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Krusader (krusader), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
