Bug 309127

Application: gwenview (2.9.1)
KDE Platform Version: 4.9.2
Qt Version: 4.8.3
Operating System: Linux 3.5.0-17-generic x86_64
Distribution: Ubuntu 12.10

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

I moved some photos from a remote storage volume with Dolphin and on the remote storage volume was left 1 broken image from those that I moved. There were still some photos on the remote storage volume and I launched a slideshow in gwenview on those photos that I left there.
Gwenview played all good until the last photo which says "Loading '[the name of the photo]' failed Loading image failed." if I open it in Gwenview or just scroll to it without the slideshow.

Observation: If I open gwenview on this photo or scroll normally to it, after I see that "Loading image failed." I can now run the slideshow from wherever I want and when Gwenview reaches this broken image in the Slideshow mode it just display "Loading image failed." message instead of crashing and works all good.

The crash can be reproduced every time.
