Currently glade/libglade/gtkbuilder all only let you set an object as
user data, otherwise, in my experience I usually avoid using
the autoconnect feature all together, and setup signal connections
after loading the glade file (liblade offered a convenient
glade_xml_signal_connect (), which
would be easy to duplicate around gtkbuilder calls).
