Profile Manager on Server.app 2.1.1. broken

Just started out with OS X Server and I had a working Profile Manager albeit very fresh installation before the 10.8.2 and 2.1.1 update.

After the update, I get an "A Server Error has Occurred" message on logging into Profile Manager and I would have been redirected to

/profilemanager/#/user_group/

The log for profilemanager has the following entry:

I cannot tell if this is a problem with the ruby code as the log implies about user_result method being missing or whether it was caused by the postgresql update query failure.
