Bug 299211

Application: gwenview (2.8.2)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.0.0-19-generic x86_64
Distribution: Linux Mint 12 KDE

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

I've scroll (by middle mouse button-scroller) jpg images in "editor mode" in window view (not fullscreen). In this folder also was contained *.ldf images (lura document file images) created earlier by xnview in windows. Gwenview showed "unsupported type" nag screen on this image, and after scrolling on next *.ldf  image show second nag screen and immediatly crashes.

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