  George G.: https://developers.google.com/webmasters/ajax-crawling/docs/learn-more i`d send them this link and ask them if all this is done like google wants it

  Michael Martinez: They should verify the ip addresses. Sounds like a broken bot spoofing googlebot. Some people run fake bots from the Google cloud. Googlebot has its own ip addresses.

  Stockbridge Truslow: Somewhere in your script something is wrong. Most likely a double quote where there should be a single or vice versa. It`s not parsing the URL correctly. First, it`s not recognizing the path because the // isn`t being decoded back from the x5C/x5C/ value that is used to store it in the database. It is that code there that says, "Start over from the top". Without those being parsed and decoded, it`s starting at the path of the script doing the execution and appending the URL there. Not sure what script that would be - I`d probably start looking for Lazy Load since that`s the most common ajax script used for images, but really - it could be anything.
