[libnice] How to properly use the function nice_agent_get_io_stream()

[silvio]

Hi

When I try to connect two machines, they don't connect unless I use
nice_agent_attach_recv() before they try out candidates. However, I
think this interferes with nice_agent_get_io_stream() and reading from
the GIOStream. I can write to the stream but reading gives me the error:

Stream has outstanding operation.

How is this properly used? All the examples I can find are done using
nice_agent_attach_recv().
