just some update on this:
I ugraded opencv to version 2.2.0, as this was mentioned on the project
homepage, and rebuilt kipi-plugins + digikam, but nothing changed, the
recognition still does not work at all.
I do not see any error messages coming from opencv, but always the same debug
output when I scan my test album, which contains only one image with 2 faces.

Can anyone of the developers see what goes wrong here?
How could I help debugging this?
