gtk_ui_manager_get_widget() is returning the same widget from
the same ui every time you call it.

You can concievably:
    a.) Reparent this widget in multiple places in the interface;
        remember that the widget can only be viewable at one place
        at a time (see the FAQ for reparenting details)
    b.) Create another GtkUIManager for the same ui description;
        thus creating an entirely seperate instance of your
        menubar.
