KDE Platform Version: 4.13.0
Qt Version: 4.8.6
Operating System: Linux 3.13.0-27-generic i686
Distribution: Ubuntu 14.04 LTS

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

When browsing through a picture directory, I got across an empty one.

Trying to delete this, digiKam crashed

The crash can be reproduced sometimes.

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