Is window by any chance a stack variable?

gtk_widget_destroyed is a very simple convenience function. 

========
void
gtk_widget_destroyed (GtkWidget      *widget,
		      GtkWidget      **widget_pointer)
{
  if (widget_pointer)
    *widget_pointer = NULL;
}
========

Only connect it like that if you want window to be zeroed when
the window is destroyed. If "window" is a stack variable, you
almost certainly don't want that to happen.

When the window is closed, most likely there is some important
part of a calling function's stack where 'window' used to
be.
