One way to debug this (and to make sure it is the protocol violation that is causing the problem), is to use Fiddler (Http Web Proxy) and see if the same error occurs. If it doesn't (i.e. Fiddler handled the issue for you) then you should be able to fix it using the UseUnsafeHeaderParsing flag.

If you are looking for a way to set this value programatically see the examples here: http://o2platform.wordpress.com/2010/10/20/dealing-with-the-server-committed-a-protocol-violation-sectionresponsestatusline/
