Search error

We've been using node view permissions on our site to restrict viewing of "intranet" pages to authenticated users. Using Drupal 7.22 / PHP 5.3.23

After upgrading to 7.x-1.1 if a non-authenticated user used the search form, it results in an error. Reverting back to 7.x-1.0 fixed the problem. The errors were:

Warning: Division by zero in SearchQuery->execute() (line 460 of D:\extdocs\modules\search\search.extender.inc).
