Problem with face recognition

Sun Dec 25 16:15:41 GMT 2016

new update:

I used the option "detect face" only (previously was using (detect and 
recognize), and it is working better, close to 288 new faces identified, 
but digikam fialed.

I try to open it again, and as soon as I click on "unknown" in the list 
of people tags , it failed:
