Product: [Applications] digikam Reporter: Axel Krebs <axel.krebs>

Status: RESOLVED FIXED    
Severity: crash CC: caulier.gilles

Sentry Crash Report:

Description Axel Krebs 2012-09-09 13:34:50 UTC 
Application: digikam (2.8.0)
KDE Platform Version: 4.9.00 (Compiled from sources)
Qt Version: 4.8.2
Operating System: Linux 3.2.0-30-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

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

- browsing some pics
- in parallel: running services
| Scan for new items: 			done
| Vorschaubilder neu erzeugen (pre-pics"(?):	done
| rebuild fingerprints:			done in this phase, the crash occured

In the past days, I testet digiKam 2.8 extensively. 
This type of crashes occurs about seven(?) times.
When restarting digiKam, process monitor shows "saw tooth" curve, I did not observe before

In comparison to digiKam 2.6, digiKam 2.8 is appearently less stable...

The crash can be reproduced every time.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
