Subject: [PATCH] Fix "assertion 'GTK_IS_WINDOW (window)' failed"

* src/gtkutil.c (xg_frame_set_size_and_position): Remove a
gtk_window_resize call which used a wrong value type
(GdkX11Window instead of GtkWindow).  The original motivation
for that line seems to be fixed by later changes (bug#80662).
