Problem with i18nmenu

Sitemap return only current language menu items.
Language neutral items are ignored.
Same problem here with nice_menus #1332396: Incopability with i18nmenu_node module.

site_map.module line 272:

// Use menu_tree_all_data to retrieve the expanded tree.
$tree = menu_tree_all_data($mid);
if (module_exists('i18nmenu')) {
  i18nmenu_localize_tree($tree);
}

replace by:

if (module_exists('i18nmenu')) {
  i18n_selection_mode('off');
}

// Use menu_tree_all_data to retrieve the expanded tree.
$tree = menu_tree_all_data($mid);

if (module_exists('i18nmenu')) {
  i18n_selection_mode('reset');
  i18nmenu_localize_tree($tree);
}
