-- Information about the crash:
- What I was doing when the application crashed:
I was searching through directories of pictures. Found one I wanted to work with and clicked "Image Editor". Then the Program disappeared and crash report came up.

The crash can be reproduced sometimes.

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