Everything is there but clicking does not trigger/show anything.

Ok, so I know that using that button on faces will not harm the training.

What do you mean by fixed. I run Rev: 1193326 and hovering the thumbnail does 
not show any GUI or mouse-over whatsoever. Clicking on the thumbnail and 
having a look at the picture including hovering the face shows the white 
quadrangle plus the name of the tag (although I removed the tag).

I do not understand what you mean. I think I remember that "add face" would 
add a red quadrangle that I could use to mark some face manually. This 
quadrangle does not appear anymore in fact nothing happens if I click on that 
icon.

Ok, I had to explicitely enable debugging for digikam and not just compile 
with debugfull:

After that the scanning progress just moves from left to tight without closing 
or processing another picture.
