Call Apple and get it esclated. Seriously. They rarely look here, and they have become very lax with their testing.
I've personally reported 3 (and in my opinion pretty obvious had it been tested) bugs directly to them. One of them when they broke the shortname payload variable for VPN settings somewhere around the 3.0.2 update.
I'm fortunate enough that our 2 server are under AppleCare and, while they usually say software issues for client OS aren't covered, they DO seem interested in server software issues and usually you'll get esclated to the Enterprise Service Desk.
