I could supply an image where it hangs. It's quite big so I would send it to 
your private email if that's alright.

However I also noticed that if one only scans one folder after having finished 
that folder digikam scans at least one picture from another folder which is 
not selected for scanning and hangs there.

And it might be that it only hangs at the picture I can supply because it is 
the last in the folder. I'll try what happens if I rename/remove it.
