That is a wrong assumption. GIMP is not strictly a GNOME application and
doesn't use libgnomeui. Thumbnail handling in GIMP is implemented by
means of libgimpthumb.

I am willing to do the necessary changes to libgimpthumb for GIMP 2.6.
But for this particular change it would be nice to have a well-defined
migration behavior. Just saying that some code in libgnomeui is
responsible for the migration is not going to work.
