U3b7 - Network.player seems broken

Using U3b7 I am unable to get a network game going.

Things first fall down with a call to:

Debug.Log("ip: " + Network.player.ipAddress.ToString())

Nothing is output at all.

Then it looks like UdpClient.Receive() fails as well.

byte[] recData = client.Receive(ref receivePoint);

Silently fails.

Anyone having issues with networking on U3b7?

It looks as though the issue is with Threads.

Calling

Dns.GetHostEntry(Dns.GetHostName()).AddressList[0].ToString();

Works in its place. Calling Network.player outside of a thread works as well.
