valac crashes when passing e.g. Gtk.Widget.destroy to a function

When compiling e.g. the following code:

int main (string[] args) {
    var box = new Gtk.Box (Gtk.Orientation.HORIZONTAL, 2);
    box.foreach (Gtk.Widget.destroy);
    return 0;
}

valac crashes with the following output:

@ricotz says on IRC that "it should work, but vala needs to pick to correct symbol reference, in this case Gtk.Widget.destroy points to 3 incarnations method/vfunc/signal, so there seems to be some confusion and the prototype-access fails".
