Sentry Crash Report:

Description Jaap 2013-08-24 10:30:09 UTC 
Application: digikam (3.3.0)
KDE Platform Version: 4.11.00
Qt Version: 4.8.4
Operating System: Linux 3.8.0-29-generic i686
Distribution: Ubuntu 13.04

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

I was scanning my compleet library for faces. Durring this processs I started confirming recognized faces. I think it might be related to a hit in the same tag as that I was editing. Since the window will be refreshed twice at the same time.

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