Bug 425230

SUMMARY

Now I tried to scan for faces a large set of pictures, around 400. I basically selected them in the search view, right clicked, and selected "Scan for faces". After a few seconds, Digikam closed itself. I have been able to replicate that four times in a row.

This is what I see in the console (from the moment it starts scanning):
