yes, thumbnails storing is probably a side effect of this huge size. I
remember a thread where Francesco and Marcel speak about a problem with
dedicated thumbs DB.
To resume : something have be done between 2.1 and 2.3 to store thumb in
main DB instead dedicated one.
Try this : run digiKam in with a fresh account and look if thumb DB blow up
size when you compute all thumbnails through dedicated batch tool (look
into Tools menu). The goal is to look if this work around is always valid
or if it have been fixed with 2.3.0
