WTF is this? And why you need it? (I think you need just
MainWindow(Glib::RefPtr<Gnome::Glade::Xml>& pGlade);
if I understanrd you correctly).

Carlos> Glib::RefPtr<Gnome::Glade::Xml>& pGlade);

Carlos>     //Init Options panel OptionsPane* mpOptionsPane(mpGlade);

Carlos, here you need to construct an object of type OptionsPane from
Glib::RefPtr<Gnome::Glade::Xml>, so you need to write:

OptionsPane* mpOptionsPane = new OptionsPane(mpGlade);

and then delete it when it not needed anymore:

delete mpOptionsPane;
