Bug 349712

Application: gwenview (4.14.0 pre)
KDE Platform Version: 4.14.9
Qt Version: 4.8.5
Operating System: Linux 4.1.0-desktop i686
Distribution: "openSUSE 13.1 (Bottle) (i586)"

-- Information about the crash:
- What I was doing when the application crashed:
1) klicked on a jpeg file in Dolphin => Gwenview started up and displayed the picture
2) switched over to the "overview" view => Gwenview started loading/showing the thumbnails
=> Crash after a few seconds

The crash can be reproduced every time.

-- Backtrace:
Application: Gwenview (gwenview), signal: Segmentation fault
