This two warnings present to me each time I want to edit a Product Review content type (as seen in the book Using Drupal):

* warning: Division by zero in /var/www/drupal/sites/all/modules/fivestar/fivestar.module on line 1587.
* warning: Division by zero in /var/www/drupal/sites/all/modules/fivestar/fivestar.module on line 1588.
