-- Information about the crash:
I do simple things, at the moment I only crop images for a screenshot database at work. On every second crop & save (CTRL+X, simple crop) digiKam IE crashes. This is NOT true for showFoto, so it must be digikam related.

The crash can be reproduced some of the time.

 -- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
