The following repro uses HttpWebRequest.Host setter which causes the exception
pasted later:

-----
using System;
using System.IO;
using System.Net;
using System.ServiceModel;
using System.ServiceModel.Channels;

public class Test
{
    public static void Main ()
    {
        var hr = (HttpWebRequest) WebRequest.Create (new Uri
("http://localhost:8080"));
        hr.Method = "POST";
        hr.ContentType = "text/xml; charset=utf-8";
        hr.Host = "localhost:8080";
        hr.Headers ["SOAPAction"] = "\"urn:foo\"";
        var rs = new StreamWriter (hr.GetRequestStream ());
        rs.WriteLine (@"<s:Envelope
xmlns:s='http://schemas.xmlsoap.org/soap/envelope/'>
<s:Header>
<To s:mustUnderstand='1'
xmlns='http://schemas.microsoft.com/ws/2005/05/addressing/none'>http://localhost:8080/</To>
</s:Header>
<s:Body />
</s:Envelope>");
        rs.Close ();
        var rr = new StreamReader (hr.GetResponse ().GetResponseStream ());
        Console.WriteLine (rr.ReadToEnd ());
        rr.Close ();
    }
}

(Run "nc -l -p 8080" on another terminal in case you want to see complete
request.)

$ mono --debug x.exe

(It's not precisely the latest master, but I assume it would still happen.)

Might be Windows-only issue.
