-- 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:
