[Digikam-users] personal-tags ar no longer stored

[AW]

Hallo,
in the last days the procedure to tag pictures does not work. Usually I choose 
a tag and press the button "apply". The tag then is seen at the buttom of the 
thumnail in italic blue letters. I don't know why this doesn't work.
If I look at the XMP-data, I can only see the last tag, not all the desired 
one.
Does it possible depend on the size of digikam.db? It's now about 68 MB. Could 
this be a border for SQLlight?
