I do not see this on my 6.4 setup. Possibly you have inconsistent
ACL data in your database --- like the example someone saw recently
where deleting a group name that was still referenced by an ACL
would make ACL display crash. (I think this got fixed post-6.4...
or maybe it's still an outstanding bug?)
