Once you invoke a method that returns this type it
will try to discover its' type at runtime using
gtk_type_name(GTK_OBJECT_TYPE(peer)).  This will
fail on a GDK object.  There also is a call
to GTK_IS_OBJECT().  There is no runtime type
identification of GDK objects and hence the 
"define-boxed".  This has been addressed to a 
large extent in Gnome 2 but I will not have a
release that supports Gnome 2 until late January.
