Application: digikam (2.5.0)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.1.10-1.9-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I'm in the "People" tab and type a name into the name field of a face I know. I select it via mouse and then continue selecting more pictures of this face. When I selected a fair amount of pictures, I hit the "apply" button and digikam starts to tag those pictures and write the metadata back to the image files.
I guess it is in this last step that digikam crashes. This is almost reproducible now. It happens every time I tag people.

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