Looks like it's dying at

     new TcpClient(AddressFamily.InterNetwork)

in 
http://hg.rabbitmq.com/rabbitmq-dotnet-client/file/7fd0545a04f8/projects/client/RabbitMQ.Client/src/client/impl/SocketFrameHandler_0_9.cs#l83

which, on the surface of it, suggests that your system is unwilling to 
let the client speak IPv4. Can you think of a reason why that would be 
the case?

I suggest sticking that line into a mini program of its own, to see 
whether that fails too.
