Application: digikam (4.0.0)
KDE Platform Version: 4.13.0
Qt Version: 4.8.6
Operating System: Linux 3.13.0-27-lowlatency x86_64
Distribution: Ubuntu 14.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I just clicked on a folder on the tree on the left. It then crashed. Previously I had a problem with it freezing when starting, so I renamed the database files and restarted and it seemed okay for a while until it crashed.

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