--- Comment #1 from Thomas Rother <t.rother at netzwissen.de> ---
The original crash was caused by a missing vdpau_drv_video.so. 
With installed VDPAU Driver Bridge for NVidia  driver we get the following
lines:

...
libva info: va_openDriver() returns 0
digikam.facedb: FaceDB SelectFaceSetting val ret =  0
digikam.facedb: FaceDB SelectFaceSetting val ret =  0
