原因
Googlebot is attempting to fetch a URL it has parsed out of a Fisheye webpage, and making a hash of it (the URL is only designed to be accessed as part of an AJAX request via JavaScript) but it is used in a way it was never designed to be called.
ソリューション
Set up a robots.txt file on the server, and disallow that particular URL prefix:
User-agent: Googlebot
Disallow: /changelog-ajax/
