gnotification under win32

[Andrea Zagli <azagli libero it>]

gnotification works under win?

i get a segfault on g_application_send_notification  
(GLib-GObject-CRITICAL **: g_object_new: assertion 'G_TYPE_IS_OBJECT  
(object_type)' failed)

or i did't uderstand how use it?

i tried with this code (i also tried without gtkapplication, but only  
with gapplication)

#include <gtk/gtk.h>

static void
print_hello (GtkWidget *widget,
             gpointer   data)
{
        g_print ("Hello World\n");

        GNotification *notification;

        notification = g_notification_new ("Lunch is ready");
	g_notification_set_body (notification, "Today we have pancakes and  
salad, and fruit and cake for dessert");
	g_application_send_notification (G_APPLICATION((GtkApplication  
*)data), "lunch-is-ready", notification);
        g_object_unref (notification);
}

static void
activate (GtkApplication *app,
          gpointer        user_data)
{
  GtkWidget *window;
  GtkWidget *button;
  GtkWidget *button_box;

  window = gtk_application_window_new (app);
  gtk_window_set_title (GTK_WINDOW (window), "Window");
  gtk_window_set_default_size (GTK_WINDOW (window), 200, 200);

  button_box = gtk_button_box_new (GTK_ORIENTATION_HORIZONTAL);
  gtk_container_add (GTK_CONTAINER (window), button_box);

  button = gtk_button_new_with_label ("Hello World");
  g_signal_connect (button, "clicked", G_CALLBACK (print_hello),  
(gpointer)app);
  g_signal_connect_swapped (button, "clicked", G_CALLBACK  
(gtk_widget_destroy), window);
  gtk_container_add (GTK_CONTAINER (button_box), button);

  gtk_widget_show_all (window);
}

int
main (int    argc,
      char **argv)
{
  GtkApplication *app;
  int status;

  app = gtk_application_new ("org.gtk.example", G_APPLICATION_FLAGS_NONE);
  g_signal_connect (app, "activate", G_CALLBACK (activate), NULL);
  status = g_application_run (G_APPLICATION (app), argc, argv);
  g_object_unref (app);

  return status;
}


thanks in advance
