QtDBus is a separate *.so

And the GIO manual still says: "GIO is striving to provide a modern,
easy-to-use VFS API that sits at the right level in the library
stack." :-)

As I'm reading the word Gtk+ here more often: I still believe that a
VFS API shoudn't be tied to a certain UI toolkit. That would be
repeating the mistake KIO did. What about Mozilla, OpenOffice, VLC and
many many others. They should all link GIO (as a VFS API). If libgio
dupulicates too many things they already have, they might be put off.
