This can be done independently of nepomuk.
When you move or delete a file using KIO, a dbus signal is emitted (see 
KDirNotify).
Well, ok, there is nothing running all the time to listen to that, we could 
just handle thumbnails in the kio move/delete jobs directly (e.g. calling a 
static method in previewjob.cpp, to keep all the thumbnail-related code 
together).
