Thanks; that was very helpful. In my situation, the name owner is a
service; so, it shouldn't change. In that case it seems I should be
using _new_for_name_owner.

But, (not really unexpectedly) changing to _new_for_name_owner doesn't
change the problem I'm having at all. :-/

Argh. Going back to this, I think I see the problem:

        dbus_g_proxy_new_for_name(
            VRML_CONTROL_FACTORY_GET_CLASS(control_factory)->connection,
                "org.openvrml.VrmlControlFactory",
                host_obj_path,
                "org.openvrml.VrmlControlHost");

The name "org.openvrml.VrmlControlFactory" is owned by the *hosted*
process; the interface "org.openvrml.VrmlControlHost" is supported by
the *host* process.

After requesting a name for the host process and using that instead,
things seem to be working.
