Indy Redirect results in 404

Indy Redirect results in 404

When I set hoTreat302Like303 and login in Gmail it results in:
First chance exception at $76F3C41F. Exception class
EIdHTTPProtocolException with message 'HTTP/1.1 404 Not Found'
Which is a problem because if I remove it then I cannot login in to
Facebook. I am quite sure this is a bug in Indy 10. I am using the latest
SVN.
