Product: [Applications] digikam Reporter: toni
Component: Faces-EngineAssignee: Digikam Developers <digikam-bugs-null>
Status: RESOLVED FIXED

Sentry Crash Report:

Description toni 2012-06-13 20:56:24 UTC 
Application: digikam (2.5.0)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I turned a picture left and edited a face tag on the same picture afterwards (I moved and resized it). In the menu on the left side, I was in the person menu at the person I was editing. When clicking on OK (in the tag edit window) the program changed something in the preview line at the top and crashed at the same moment.

The crash can be reproduced some of the time.

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