Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Open a dir with some foto with some face recognized in "view image" mode
Move the mouse on a face recognized
Press spacebar to switch to the next file ... and DK crashes!! :(

the pakages are from the following repo
ppa:philip5/extra
ppa:philip5/kubuntu-backports
ppa:kubuntu-ppa/backports

The crash can be reproduced every time.

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