-- Information about the crash:
- What I was doing when the application crashed:
I've recently seen a number of crashes in DK when thumbnails are shown and I've selected one and/or scrolled the tumbnail pane. Perhaps once an hour if I'm working through a batch of pictures.

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