application/json - additional security concern?

Regarding:

  http://www.ietf.org/rfc/rfc4627.txt

I recently noticed a blog entry and claim of a potential security vulnerability
with application/json data, posted here:

  http://bob.pythonmac.org/archives/2007/04/05/fortify-javascript-hijacking-fud/

I've not analyzed the details, but there's a clear implication of a potential
but easily defended route to exploitation in some browsers.

One of the examples in RFC 4627 (the array example) appears to be of a form that
the article claims is vulnerable.
