i18ntaxonomy conflict

Hi,
I don't know exactly the cause, but it seems to be someting wrong between vocabindex and i18ntaxonomy
It has something to do with this function

function vocabindex_menu_alter(&$items) {
  $vis = vocabindex_vi_load(VOCABINDEX_VI_PAGE);
  foreach ($vis as $vi) {
    if ($vi->view == VOCABINDEX_VIEW_FLAT) {
      $item = &$items['taxonomy/term/%'];

      // Store the original configuration, so we can pass it on to our own
      // callback.
      $callback = $item['page callback'];
      $arguments = $item['page arguments'];
      $file = $item['file'];
      $filepath = isset($item['file path']) ? $item['file path'] : drupal_get_path('module', $item['module']);

      // Alter the original callback.
      $item['page callback'] = 'vocabindex_term_page';
      $item['page arguments'] = array_merge(array(2, $callback, $file, $filepath), $arguments);
      $item['file'] = 'vocabindex.module';
      $item['file path'] = drupal_get_path('module', 'vocabindex');
      break;
    }
  }
}

specialy at this line :
$item['file path'] = drupal_get_path('module', 'vocabindex');

When both modules are activated, and I click on a term link, I get this error
Fatal error: require_once() [function.require]: Failed opening required 'sites/all/modules/vocabindex/i18ntaxonomy.pages.inc' (include_path='.:/usr/local/lib/php') in /home/web/www/drupal/includes/menu.inc on line 346

For the moment, as a workaround, I've just commented the entire vocabindex_menu_alter function.
