Thanks very much for the test code. I have now fixed this - It happened with
on-stack child widgets that don't derive from Gtk::Container. It was a just  a
silly cut-and-paste typo error. This fixes at least 2 other known bugs. I know
I'm relieved.

	* Gtk::Container_Class:destroy_callback(): dynamic_cast<> child
	widgets to Widget*, instead of Container*, of course. This seems to fix
	lots of lifetime bugs.
