new System.Net.WebClient ().DownloadData (url) always timeouts instead of
downloading the data.

Reproducible: Always

Steps to Reproduce:
1. cat > a.cs << EOF
public class MainClass {
    public static void Main (string[] args) {
        var clt = new System.Net.WebClient ();
        clt.DownloadData ("http://www.google.com/");
        System.Console.WriteLine ("OK");
        System.Environment.Exit (0);

2. gmcs a.cs
3. mono a.exe
Actual Results:  
[2.6.3] ~> mono --debug a.exe

** (a.exe:30342): WARNING **: Missing method .ctor in assembly

[0x00000] in
  at System.Net.WebClient.DownloadDataCore (System.Uri address, System.Object
userToken) [0x0000a] in

Expected Results:  
The application should output "OK". No timeout is expected if network
connection is ok (mine is).

The "Actual Results" output indicates I am using mono 2.6.3 and that is the
However I have also tried mono 2.6 branch HEAD (r155611) and it fails in the
same way.

Mono 2.6.1 works ok. Mono 2.6 branch r150544 also works ok.
