-- Information about the crash:
- What I was doing when the application crashed:

Basically just using the space and Backspace key to move to the next/previous image in the Edit window. at some point, after a few photos it always crashes.

The crash can be reproduced sometimes.

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