So perhaps we should be hooking into NetworkManager differently? We have
DBus support already, so that shouldn't be a problem for us like it
might be for FireFox.

DBus threading... I was afraid of that. There was recently a RedHat
bugzilla bug on a similar issue in Gaim. I don't have the number
off-hand, but maybe Warren does. It was something with deadlocks because
the GTK+ file chooser would init the vfs library, which used threads,
and DBus used threads, and the initializations didn't play well
together. IIRC, eventually this was fixed in DBus, so maybe this isn't a
problem with newer versions of DBus?
