This is because if you exceed the URL length limit that Google has imposed on all of its services as a security precaution, rather than returning Javascript which would ultimately trigger your callback, the servers instead respond with a standard error message saying that the request URI was too long. What I would do is use Firebug to examine the net requests, subtract the number of characters in the request uri (not including the query string) from 2,000 (i.e., the uri length limit), and test the length of your query string (be sure to uri encode it first!) against that remainder. Then you'll know if your url will be too long before you ever make the request.
