Anyone get the 5.1u1 update to the vcenter service appliance to work?

Hi folks:

I was trying to update the vcenter server appliance from 5.1b to 5.1u1 and the update fails.  The log (/opt/vmware/var/log/vami/updatecli.log) is full of errors like the following that just keep repeating:

I tried doing the update both via download from the internet, and by downloading the iso file and applying it from there.  Same result both times.  Had to go back to the snapshot prior to the upgrade.   Anyone have any success applying this update?
