Bug 280521

Application: digikam (2.1.0)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-10-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
What did I do:
- Scanned all my pictures for faces (around 24000)
- After a restart of digikam, displayed unrecognized faces
- Scrolled to a folder where two pictures where listed in the faces view, both of which were falsely recognized (they didn't contain any faces)
- Marked both pictures as containing no faces (using the "-" button at the bottom of each picture
- I clicked on the second picture relatively fast after the first  picture had been removed and the screen had been redrawn
- The crash happened very fast after clicking on the second picture

System:
- Ubuntu Natty
- KDE 4.7.0 from ppa:kubuntu-ppa/backports
- various libraries from http://ppa.launchpad.net/philip5/extra/ubuntu
- Digikam compiled from current git, v2.0.0-180-gaf06c4b, or af06c4b16c443bda20f6aa423dd474a1e6a869f8 to be precise.

I'm happy to test any patches/git branches if this helps you.
