'recent' CiviMails not visible on Multilingual site

Some CiviMails are inaccessible on a Multilingual site (these are more recent ones but I can't pinpoint the change incident).

In the civicrm_mailing_group table some rows have an entity_table of 'civicrm_group' whereas others have 'civicrm_group_en_US'. (The more recent ones have the second).

The ACL clause restricts accessible mailings to those where entity_table = 'civicrm_group'. I'm not sure if this is a storage or retrieval problem but the easiest & safest fix appears to be changing this to entity_table LIKE 'civicrm_group%'
