Description MarcP 2022-11-03 16:29:34 UTC 
SUMMARY
I have noticed that many of the people in my People list do not have a face thumbnail/icon assigned to their face, despite several faces being available.

I believe that happened because these people were not added inside digikam, but instead they were imported from pictures that already had that metadata with people in it (or a folder was temporary unavailable and then rescanned again). In that case, the person is left without a face thumbnail.

Another case would be when the face that corresponds to the face icon is deleted, and that person is left without a face. 

I believe in these cases, there should be some kind of process that checks for faces with missing icons and assign one among the available ones.


STEPS TO REPRODUCE
1. Tag a face rectangle in a picture not using digikam (or using another database).
2. Import that picture into digikam.
3. Observe the icon for that person in the People list.

OBSERVED RESULT
That person does not have an icon for their face.

EXPECTED RESULT
If the person does not have yes icon, assign one among the available ones.
