[Digikam-devel] [digikam] [Bug 338785] Digikam face detection finds no faces

--- Comment #2 from Jens B. Benecke <jens-bugs.kde.org at spamfreemail.de> ---
I did as you said:
- turned on KFACE debug (51005 or something)
- started digicam from a console
- went to the faces sidebar
- clicked on "Search for faces"
- selected "detect and recognize" and "delete old training data" in the options
- clicked OK
- At once I got a small popup window saying the operation is completed and took
00:00:00 seconds.
- Also in the "My Tags" sidebar below the face detection button there are no
tags, although my photos have lots of tags already.

Here is the console output. I don't see anything suspicious except for
" digikam(1098)/KIPI (general): Current image collection is not valid.  ". What
does that mean?
