Application: gwenview (2.10.0)
KDE Platform Version: 4.9.90
Qt Version: 4.8.4
Operating System: Linux 3.7.0-desktop-0.rc8.1.mga3 x86_64
Distribution: "Mageia 3"

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

Gwenview crashed a few times while opening any image file on a specific directory (approx. 1/20 chance). This happened at least when using the "next file" button and when double-clicking an image in the thumbnail view.

Unfortunately I can't provide a file list of the directory in question, and it seems that while writing this it became no longer reproducable. With a quick look I do not see any strange characters in the file names except parantheses and '%' characters.

Maybe the backtrace yields some useful info for you...

The crash can be reproduced some of the time.
