I put that one down to being used by a botnet that is looking for guestbooks and comment pages to post to. It comes from a variety of IP addresses and usually has the referrer set to the page it is requesting (self referring). The same IP address will use a variety of other Fake UA's (currently I know 112). Check that IP address in Project Honeypot and they will probably have labeled it a Comment Spammer.
