Column name change civicrm_mailing.visibility not reflected in views - breaks multilingual

column rename in upgrade script does not change definition of multilingual views based on the column resuting in a broken view (symptom is that the database fails to backup as it fails on that view)

From script:

{if $renameColumnVisibility}

ALTER TABLE `civicrm_mailing` CHANGE `visibilty` `visibility` ENUM( 'User and User Admin Only', 'Public Pages' ) CHARACTER SET utf8 COLLATE utf8_unicode_ci NULL DEFAULT 'User and User Admin Only' COMMENT 'In what context(s) is the mailing contents visible (online viewing)';

{/if}
