invalid column name 'xml_index_type'

Hi, 

I'm not sure when this started happening but today, none of us using SSMS 2012 connected to SQL server 2012 SP1 were able to script any objects.  we are presented with the message

Failed to retrieve data for this request. (microsoft.sqlserver.management.sdk.sfc)
Invalide column name 'xml_index_type'.

see screenshot.

wondering if any ran into this before and have a fix?

Thanks
