I thought of one specific problem that might not be obvious at first glance.
If the BonoboControl is also a BonoboZoomable, then the BonoboZoomableFrame
will be holding a reference to the object too, so the unref in
bonobo_control_plug_destroy_event_cb won't be sufficient to make the object
get destroyed.
