Users without 'answer question' permission can't choose 'category'

At least in my case now another bug is open:

Fatal error: [] operator not supported for strings in drupal-6.10/sites/all/modules/faq_ask/faq_ask.module on line 451

Proposed fix:

(file: faq_ask.module, line 444...)

      if ($params['category'] == -1) {
        $body = t('The following question has been posted.', NULL, $language->language);
      }
      else {
        $body = t('The following question has been posted in the "!cat" category.', array('!cat' => filter_xss($term->name)));
      }

into

      if ($params['category'] == -1) {
        $body[] = t('The following question has been posted.', NULL, $language->language);
      }
      else {
        $body[] = t('The following question has been posted in the "!cat" category.', array('!cat' => filter_xss($term->name)));
      }

--edit: I apologize, this should have gone to (and in fact now is) at #338165: "Give" anonymous page to expert.. I should avoid using multiple tabs.
