Hi,

I've saw some examples about this problem and tried it with no luck. i
saw that the object was cast and just added.
i've tried:
GtkAction*
menu_action_new (const gchar *name,
                const gchar *label,
                Model *model)
{
       GtkAction* action;
       _thunar_return_val_if_fail (name != NULL, NULL);
       _thunar_return_val_if_fail (label != NULL, NULL);

       action = g_object_new (MENU_TYPE_ACTION,
                                          "hide-if-empty", FALSE,
                                          "label", label,
                                          "name", name,
                                          NULL);

       MENU_ACTION(action)->items = model;

       if(G_TYPE_FUNDAMENTAL (action) == G_TYPE_OBJECT)
       {
               g_message(model->menu->name);
               g_message(action->items);
               g_message("test");
       }
       return action;
}
but it seems the second g_message won't print, it gives an segmentation fault.

extra info: #define MENU_ACTION(obj)
(G_TYPE_CHECK_INSTANCE_CAST ((obj), MENU_TYPE_ACTION,
MenuTemplatesAction))

What am i missing here?

Thanks in advance
