The handler on the destroy event needs to "eat" the
signal that caused it by returning TRUE. If you don't
do that then the delete event signal will be
propagated and somewhere further along in the handler
chain the default delete event handler will generate a
destroy event, which will then destroy the window. So
you need to roll a little callback that wraps
gtk_widget_hide and returns TRUE and hook it up to
delete event.
