It seems that I have the same here, face scanning seems to work fine until it
reaches a folder with a mix of videos and images. 

Using digikam-2.0.0-beta4 (debug build) on Gentoo / KDE-4.6.1, running through
gdb.

I disabled the checkbox "use all cores" in the scanner options and closed all
kinds of album/preview windows to reduce risk, but still reproducibly the same
crash.

My backtrace is a bit different:

-------------------------

Is this enough or should I provide more traces?
