[From bug #688007]

However, WebClient is still not working! I checked out your changes and made
further tests. As I pointed out in one of my previous posts, there seems to be
a problem with proxy access. If a system proxy is set up, WebClient get's
totally confused. The following list shows how to reproduce the issue:

1. Setup up a system wide proxy
2. Call OpenRead() to open an anonymous ftp connection to a site on the

FtpWebRequest.OpenControlConnection() calls Socket.Connect() to connect to the
proxy server. But instead of using the correct proxy port, it chooses port 21.
As a result, the proxy cannot respond and WebClient.OpenRead() fails.

I am running Ubuntu Maverick but I guess the result should be the same when
running under Suse.
