If widget->window != NULL, then GDK_WINDOW_XWINDOW(widget->window)
will definitely return a real X window. You can't have a GdkWindow
that lacks an X window. widget->window is always non-NULL if the
widget is realized.

(Basically, I think there's a bug somewhere - I would guess in your
test case, as I've never seen this issue reported against GTK.)
