Bug 326131

Application: gwenview (4.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.6
Operating System: Linux 3.11-4.dmz.1-liquorix-amd64 x86_64
Distribution: Debian GNU/Linux experimental (sid)

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

I was browsing photos and opened directories in left pane one-by-one. I have browsed ~10 directories and after that gwenview had crashed. 

I've tried to reproduce the issue, but no luck.

The crash does not seem to be reproducible.

-- Backtrace:
Application: Gwenview (gwenview), signal: Aborted
