                $admin_group = db_query("SELECT user_id FROM user_group
                WHERE group_id=".$this->getID()." AND admin_flags='A'");
                if (db_numrows($admin_group) > 0) {
                        $idadmin_group = db_result($admin_group,0,'user_id');
                }
                if (!$mlist->create('commits','Commits',1,$idadmin_group)) {
                        $this->setError(sprintf(_('ML: %s'),$mlist->getErrorMessage()));
                        db_rollback();
                        return false;
                }

when "if (db_numrows($admin_group) > 0)" not is true it won`t set $idadmin_group.
