Application: gwenview (2.5.0)
KDE Platform Version: 4.5.00 (KDE 4.5.0) (Compiled from sources)
Qt Version: 4.6.3
Operating System: Linux 2.6.35.2-notux i686
Distribution: Debian GNU/Linux 5.0.5 (lenny)

-- Information about the crash:
I actually found the crash when using akregator reading a blog post, and sometimes while surfing with konqueror. But since looking at the backtrace it seems a gwenview issue I rather file the bug here.

- What I was doing when the application crashed:
While running:
$ gwenview http://lh4.ggpht.com/_DsEzMwoRlb4/TGsDfHGAmII/AAAAAAAAAaM/LD_Pr8r6S6A/fy-bug-kalgebra.jpg

Every time the program crashes. I found the issue with other images as well.

The crash can be reproduced every time.

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