[Glade-users] Widget insert problem with libglade


I have this code on my app:


accel_group = gtk_accel_group_new ();

  xml_glade = glade_xml_new (GLADE_PATH "mywindow.glade", NULL, NULL);
  interface.window = glade_xml_get_widget (xml_glade, "mainwindow");
  gtk_window_add_accel_group (GTK_WINDOW (interface.window), accel_group);
  interface.vbox = glade_xml_get_widget (xml_glade, "vbox");
  interface.handlebox = glade_xml_get_widget (xml_glade, "bonobodockitem2");
  interface.statusbar = glade_xml_get_widget (xml_glade, "appbar1");
  interface.statusbar_pb = (GtkWidget *) gnome_appbar_get_progress ((GnomeAppBar *) interface.statusbar);
  view_statusbar_menu = glade_xml_get_widget (xml_glade, "menu_statusbar1");
  interface.save_as2 = glade_xml_get_widget (xml_glade, "save_output1");
  interface.scrolledwindow = glade_xml_get_widget (xml_glade, "scrolledwindow1");
  interface.autorefresh_frame = glade_xml_get_widget (xml_glade, "autorefresh_frame");
  interface.change_settings_sub_menu = glade_xml_get_widget (xml_glade, "change_settings");
  interface.combobox_lists = glade_xml_get_widget (xml_glade, "combobox_lists");

  /* autorefresh widgets */
  interface.spin1 = glade_xml_get_widget (xml_glade, "spinbutton1");
  interface.spin2 = glade_xml_get_widget (xml_glade, "spinbutton2");
  interface.progressbar = glade_xml_get_widget (xml_glade, "progressbar1");
  interface.start = glade_xml_get_widget (xml_glade, "start_button");
  interface.stop = glade_xml_get_widget (xml_glade, "stop_button");
  interface.autorefresh_button = glade_xml_get_widget (xml_glade, "autorefresh_button");

  /* search */
  interface.search_button = glade_xml_get_widget (xml_glade, "search_button");
  interface.search_entry = glade_xml_get_widget (xml_glade, "search_entry");
  interface.combox = glade_xml_get_widget (xml_glade, "combobox");
  gtk_combo_box_set_active (GTK_COMBO_BOX (interface.combox), 0);

  glade_xml_signal_autoconnect (xml_glade);


this code works, and it generates a main window with an internal vbox. Vbox has 5 "elements".
When I append below code to put hpaned in the one only empty element of vbox (third element):

interface.hpaned = gtk_hpaned_new();
gtk_container_add (GTK_CONTAINER(interface.vbox), interface.hpaned);
gtk_widget_show (interface.hpaned);

I got a run time error, hpaned is not showed and app crashes...

From gdb:
#0  0x0000002a975e4593 in g_type_check_instance_is_a () from /usr/lib/libgobject-2.0.so.0
#1  0x0000002a975d15f4 in g_object_ref () from /usr/lib/libgobject-2.0.so.0
#2  0x0000002a9683bee1 in gtk_widget_show () from /usr/lib/libgtk-x11-2.0.so.0

Is not possible make this adding with libglade???
