    It only exposes an error if uncommenting the set_flags() line
    if you don't add the refcount:

        Gtk-WARNING **: invalid unclassed pointer in cast to `GtkWidget'

        Gtk-CRITICAL **: file gtkobject.c: line 1172 (gtk_object_unref): assertion \
`GTK_IS_OBJECT (object)' failed.

    Ie:
        $button->set_flags(GTK_VISIBLE | GTK_HAS_GRAB);
        $button->ref();

    works.
