Ah, that clears things up. Thanks.

Oh, OK. I got the impression that libwnck does the right thing since all
the enums/flags in wnck.defs does have gtype-ids... it might be my
inexperience with GTK+/GNOME that's shining through though :-)

On to the next problem then (which I sent in another email as well),
where do enums/flags live in the python bindings? I need to instantiate
and pass some flags into a libwnck function.
