Bug 350130

Application: digikam (4.11.0)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.13.0-57-generic x86_64
Distribution: Ubuntu 14.04.2 LTS

-- 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
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
