Hi,

Awesome theme! :)

Deprecated function: Call-time pass-by-reference has been deprecated in _theme_process_registry() (line 549 of /home/server/.drupal/7/development/drupal-7.12/drupal-7/includes/theme.inc).

      // If the theme implementation defines a file, then also use the path
      // that it defined. Otherwise use the default path. This allows
      // system.module to declare theme functions on behalf of core .include
      // files.
      if (isset($info['file'])) {
        $include_file = isset($info['path']) ? $info['path'] : $path;
        $include_file .= '/' . $info['file'];
------->include_once DRUPAL_ROOT . '/' . $include_file;<--------------------------------------
        $result[$hook]['includes'][] = $include_file;
      }

Don't no if this is your theme or Zen causing this, but I already reported to Drupal Core, but they said its coming from the theme calling this. http://drupal.org/node/1541878#comment-5906680
