Maybe you should have a dbus_g_proxy_get_owner() to go with this, which
would normally not need to make a remote call and thus be convenient?

Be sure to try this with a clean checkout, and with srcdir != builddir

The reason for the hack is that trying to do it cleanly never seemed to
work for all the cases. GTK has some crazy complicated Makefile rules
for this kind of thing. As long as you try it and feel you understand
the issues the patch is fine, but do try it, in my experience the
obvious thing doesn't work and either always rebuilds or fails to
rebuild in certain cases I don't remember. Check for both failure modes
(always rebuilds regardless of dependencies, and never rebuilds).
Owen can probably explain the actual issues here.
