OK.  So I had used the wider rule of: QT_LOGGING_RULES=“digikam*=true” and ran 
three experiments:

 1. YuNet on pictures from January 2024, which are mostly HEIC
    ==> zero detections

Thinking that maybe file type might be an issue, I ran:

 2. YuNet on pictures from January 2008, which are all jpeg
    ==> zero detections
 
 3. YOLOv3 on pictures from January 2008
    ==> 113 detections

So, the issue appears to be confined to YuNet.  Since it works on other 
systems, likely there's an unfortunate interplay between some component 
versions on my system.

I do have that log if you want it, but I then did just as you ask -- logs for 
just digikam.face* -- and that is attached.

Best,
-Steve
