I think the patches you supplied to me to fix the header display issue
changed the line numbers.

Here it goes:
413    /* If autoexpunge is turned on, then do it now. */
414    if ($auto_expunge == true) {
415       $exp_cnt = sqimap_mailbox_expunge($imapConnection, $mailbox, false, '');
416       $mbxresponse['EXISTS'] = $mbxresponse['EXISTS'] - $exp_cnt;
417       $num_msgs = $mbxresponse['EXISTS'];
418    }
