Problem does appear to be in System.Net.HttpWebRequest:

pgrace at garden:~/mete$ mono httpwebreq.exe

Unhandled Exception: System.Net.WebException: Error: NameResolutionFailure
  at System.Net.HttpWebRequest.EndGetResponse (IAsyncResult asyncResult)
[0x00000]
  at System.Net.HttpWebRequest.GetResponse () [0x00000]
  at HttpWebReqTestCase.MaybeDNSError.Main (System.String[] args) [0x00000]


Code used:

using System;
using System.Net;

namespace HttpWebReqTestCase {
    class MaybeDNSError {
        public static void Main(string[] args)
        {
            HttpWebRequest req =
(HttpWebRequest)WebRequest.Create("http://www.google.com");

            HttpWebResponse resp = (HttpWebResponse)req.GetResponse();

            string[] names = resp.Headers.AllKeys;

            Console.WriteLine("{0,-20}{1}\n", "Name", "Value");
            foreach (string n in names)
                Console.WriteLine("{0,-20}{1}", n, resp.Headers[n]);

            resp.Close();
            Console.ReadLine();
        }

    }
}

And to show that dns does in fact work on this system:

pgrace at garden:~/mete$ host www.google.com
www.google.com is an alias for www.l.google.com.
www.l.google.com has address 66.102.1.104
www.l.google.com has address 66.102.1.147
www.l.google.com has address 66.102.1.99
www.l.google.com has address 66.102.1.103
