Sentry Crash Report:

Description Frederic Grelot 2012-03-18 15:31:21 UTC 
Application: digikam (2.6.0-beta3)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.8.0
Operating System: Linux 3.2.9-2.fc16.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
I was giving names to faces. In an image, I knew they were two people, and only one of them had been detected. I clicked on the image, used the small button to "add a face Tag". I drew the square, moved and resized it a little, and when it was at the correct place and I wanted to go back to the view with all the faces to tag... bang!

After restarting, I can see that the tag square is there, at the correct place (so the last move was beeing saved).

Digikam is in version 2.6.0-beta3 (built from source)

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

Comment 1 Marcel Wiesweg 2012-03-18 17:25:40 UTC 
The last two frames look bogus, but the backtrace seems to fit in the picture of the infamous group of crashes in that area
