Twitter Search API is returning weird characters - is it me or is it them?

Question

We are building an app that accesses the Twitter search over JSONP.

It mostly works fine, but occasionally the request returns a JSONP callback that consists of weird unparseable characters.

Here is an example: http://search.twitter.com/search.json?result_type=recent&rpp=100&geocode=51.4375857,-0.1658648,1km&page=5&callback=jsonp1272532482854

(If you change page=5 to a value less than 5 in the URL it works fine)

So

• Am I doing something wrong?

• Can anyone suggest a workaround?
