problems when closing properties dialog with windowmanager

[Pierre Pronchery <pierre pronchery defora org>]

		Hi,
	
	I'm using Dia CVS 20020422, with Gnome 1.4, WindowMaker 0.80 on
a Debian 3.0 (woody).

	This problem happens only when compiling with Gnome support.
	When I close the properties dialog with my windowmanager instead
of the close button, and then try to open it again, it fails. It seems
the properties widgets have been destroyed:

Example: I've created a new diagram, with a UML class. Double-clicked on it,
closed the properties window with my window manager on top of the
window, and then double-clicked again on the class. It sometimes
immediatly segfaults, sometimes just fails to open it again.
Here are the error messages:

I think I should have tried with a less complicated entity :)
The properties window seems to have been destroyed instead of just
hidden, or created again. This problem doesn't happen with the layer
window.

I hope this will help,
