Yes - it worked. I now do the following and the segmentation violations
go away.

		self.display = gtk.gdk.display_manager_get().get_default_display()
		self.clipboard = gtk.Clipboard(self.display, "CLIPBOARD")

I think my initial problem was calling gtk.gdk.Display() for every
copy/cut/paste operation - pygtk does not like it! Same with
gtk.Clipboard() - call it more than once and you're dead. So I call it
once at the start of the program, store the values and everything is
peachey!

Thanks for the help!


Cheers


Bob
