[Digikam-users] Digikam Face Detection does not work for me

I have nothing to do with the digikam packages in Debian Sid BUT they
forcefully remove all haarcascades and lbpcascades files that Digikam
provides and make the packages dependent on them as provided from the
opencv-data package. the opencv-data package provides them in
/usr/share/opencv/haarcascades but I'm not sure if Digikam looks for them
in any other place than the self provided files in
/usr/share/kde4/apps/libkface/haarcascades? Might be a packaging problem
with Digikam or to patch Digikam to also look in
/usr/share/opencv/haarcascades for the files...
