gtk-clutter 1.2 for windows error on non-x11 patforms.

[gontzal <txasatonga gmail com>]

I have this error on windows:
(clutter1.exe:2564): Clutter-Gtk-CRITICAL **: Embedding GtkWidget inside 
Clutter
Actor through GtkClutterActor does not yet work on non-X11 platforms.

with this code:

uses Gtk;
uses Clutter;
uses GtkClutter;

window: Gtk.Window
embed: GtkClutter.Embed ;
stage: Clutter.Actor
actorx:Clutter.Actor
init
    if (GtkClutter.init(ref args) != Clutter.InitError.SUCCESS)
        GLib.warning("Could not initialize GtkClutter")

    else
        window = new Gtk.Window();
        embed = new GtkClutter.Embed();
        var box= new Gtk.Box(Gtk.Orientation.HORIZONTAL, 5)
        box.add(embed)
        stage = embed.get_stage();

        var boton = new Gtk.Button.with_label("Label");
        var actorx = new GtkClutter.Actor.with_contents(boton);
        actorx.set_reactive(true)
        actorx.set_x(100)
        actorx.set_y(100)
        stage.add_child(actorx)

        window.add(box)
        window.set_default_size(600, 600);
        window.show_all();
        Gtk.main();

Anyone knows the reason of the error? Maybe the version? This code goes 
well on linux...
Thanks. Gontzal.
