The "gsa-crawler" means Google Search Appliance [google.com] crawler -- so it isn't googlebot, but from the email address it purports to be a Google employee doing research with their "appliance".
The gsa-crawler could be from anyone at an organization that bought the box, or even an intentional spoof I suppose.
