Subject: Jippie: file previews are generated again! Thanks to Fredrik for
 giving me a hint how to do it (if I would have known that it is so easy, I'd
 have implemented it already some weeks ago...). It's very nice that the
 details view now also is able to show previews (Kudos to Interview &
 KDirModel).
