Hi Marcel,

just testing the thumb db. Right now it seems to be slower, especially filling 
the album thumbnails in the folderview takes up to 18 seconds here.

But there is another problem: digiKam crashes when NOT using the thumb.db.
Can you reproduce this?

If you leave the code commented, digikam will die on startup.
