All Gtkmm objects inherit sigc::trackable (AFAIK), so it makes little
sense to add a reference if you create a slot for an object.  If you
_really_ want to make slot keeping object alive, you could add a
reference by hands.  If there is no standard way, I'll implement my
own, since I consider benifits (e.g. binding Gtk::Action::set_sensitive)
far more important than drawbacks of probably losing slot because object
is not used anymore.
