Some more progress but no solution yet. One (the?) problem seems to be, that 
digikam4 does not use the album column the Images table. The value is NULL for 
all entries. So digikam5 doesn't seem to find the old entries an just adds new 
ones :-(
The uniqueHash is the same for both versions of the image.

Any ideas what is causing this?
