Ok, did you take a look at the patch?

Anyway:

nxclient sends "bye"
nxclient switches its stdio to the nxproxy
nxserver send "Bye" # to confirm the bye
nxserver sends "NX> 999 Bye" # to confirm the bye 

- -> Kaboom, local nxproxy says "Cannot parse remote options string NX>"

nxserver opens up netcat, but it won't have a stdin anymore as the connection 
was already closed by the remote proxy.

Fix:

nxserver send "Bye" to stderr # to confirm the bye

the "Bye" does not go to nxproxy, but to nxclient like it should.

This of course _is_ a race condition and needs to be fixed anyway.

Could you test the patch if this solves your problems?
