calls to undefined function db_fetch_object in d7 tarball

There were a number of errors in Apache log for a D7 CiviCRM 4.1.2, 4.1.4 and 4.1.5 site:

PHP Fatal error: Call to undefined function db_fetch_object() in /var/www/mysite/public/modules/php/php.module(80) : eval()'d code on line 10

db_fetch_object is only defined in D6, not D7.

Checking with
$ grep -R db_fetch_object *

sites/all/modules/civicrm/CRM/Core/Permission/Drupal.php: while ($result = db_fetch_object($query)) {
sites/all/modules/civicrm/drupal/api.php: if (!db_fetch_object($roles_result)) {
sites/all/modules/civicrm/drupal/modules/civicrm_rules/civicrm_rules.participant-eval.inc: while ($result = db_fetch_object($results)) {

The civicrm_rules files refers to cck in a comment just above the db_fetch_object call, so that may not be a bug. It was not enabled on our site.
