[Vala] Glade problem

["Arley Consuegra Rosello" <aconsuegra estudiantes uci cu>]

I'm have the next code .

using Gtk;
class ig.Principal: GLib.Object {
        private Window vtnaPrincipal;
        private Assistant asistenteDHCP;

construct {
var iuGlade=new Builder();
iuGlade.add_from_file("/home/aconsuegra/Projects/hconfr/hconfr/interfaz/interfaz.glade");
iuGlade.connect_signals(null);
this.vtnaPrincipal = iuGlade.get_object ("vntPrincipal") as Window;
this.asistenteDHCP = iuGlade.get_object ("asistenteDHCP") as Assistant;
          }

   
                                                  
   public void mostrar_asistente_dhcp(){

    this.asistenteDHCP.show_all();
        stdout.printf ("Entra");

                                                           
                                                   }

}


When I run de application and click a button in the window the signal clicked call to
mostrar_asistente_dhcp()
then the application crash with signal  SIGSEGV
I'm using debian unstable, valac 0.7.0-1 and glade-3 3.6.2 and using gtkbuilder
What is the problem?
