Question about SOAP Faults and HTTP Response

I am returning SOAP faults to our clients, but I'm confused as to how these are formatted with HTTP. In the HTTP response, should the content length be specified by a Content-Length header? Right now, I see the length returned as part of the content but it is formatted in hex and is sent after a CR/LF (see below). I have a user who is using a ruby soap library that seems to be ignoring the content returned in the fault message. I'm wondering if this is caused by a malformed HTTP response.
