public function buildBreadcrumb($term) {

  // Build breadcrumb like core does.
  // @see taxonomy_term_page()
  $current = (object) array(
    'tid' => $term->tid,
  );
  $breadcrumb = array();
  while ($parents = taxonomy_get_parents($current->tid)) {

    // Allow modules like i18n_taxonomy to alter the parents.
    drupal_alter('taxonomy_display_breadcrumb_parents', $parents);
    $current = array_shift($parents);
    $breadcrumb[] = l($current->name, 'taxonomy/term/' . $current->tid);
  }
  $breadcrumb[] = l(t('Home'), NULL);
  $breadcrumb = array_reverse($breadcrumb);
  drupal_set_breadcrumb($breadcrumb);
