	gtk_widget_destroyed  takes one parameter, so you would need 
	to use the "gtk_signal_connect_object" function instead of
	                "gtk_signal_connect".  But please read on ... :*)

	But reguardless, you are trying to call the gtk_widget_destroyed
function
	on the "dlg" widget when the "dlg" widget is destroyed.
	I'm surprised that this worked in 1.0.5. 

	So Not fully knowing the internals of GTK, I believe that you 
	are calling the destroy operation on widget that has already been
	destroyed. Thus the "NULL" result!

	I had a similar problem in 1.0.6. (I'm still using the so called
"stable" version)

	^^^^^^^
	This is the first time the widget is destroyed!

	No but I have lots of opinions ;)
