PHP 5.4 Include Bug

Ran into the following error after updating to PHP 5.4:

warning: include_once(/home/user/public_html/h/mydomain.com): failed to open stream: No such file or directory in /home/user/public_html/h/mydomain.com/includes/unicode.inc on line 339.
warning: include_once(): Failed opening '' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/user/public_html/h/mydomain.com/includes/unicode.inc on line 339.

Disabling Nodewords basic meta tags gets rid of the error message, but it will reproduce upon re-enabling that sub-module.

Googling it came up with: https://www.drupal.org/node/1028730 which leads to the discussion that the "path is changed before Drupal shudown".

Wonder if the problem lies in line 876 of nodewords.module?

  if (empty($tags_info)) {
    // Allow third-party modules to alter the  meta tags list, or to add new
    // meta tags.
    foreach (module_implements('nodewords_tags_info') as $module) {
      if (module_hook($module, 'nodewords_api')) {
        $info = module_invoke($module, 'nodewords_api');
        $version = '0.0';

        if (isset($info)) {
          if (is_string($info)) {
            $version = $info;
          }
          elseif (is_array($info) && isset($info['version'])) {
            $version = $info['version'];

            if ($load && !empty($info['file'])) {
              $include_file = $info['file'];

              if (isset($info['path'])) {
                $include_file = $info['path'] . '/' . $include_file;
              }

              include_once $include_file;
            }
          }
        }

No idea where to go from here... :-/
