Bug 264605

Application: gwenview (2.6.0)
KDE Platform Version: 4.6.00 (4.6.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.37-candela x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
I open the photograph, turn it 90 degrees left and save it. When I choose an option Plugins - > Batch Processing -> Colours of the photo (I have a polish version of Gwenview, so i don't know the true name of the last position in english) i have a crash of the program.

The crash can be reproduced every time.

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