Looks good for you, not for me ;)  That means that my trivial fix isn't
going to catch it.

Next:

SELECT * from ACL, CachedGroupMembers, Groups where ACL.RightName = 'OwnTicket' and ACL.PrincipalId = Groups.id and Groups.id = CachedGroupMembers.GroupId;

This will generate a _lot_ of data. Probably best not to CC the list on
the full response.
