Reconnecting to session hangs with "Session didn't become ready in time" message

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Disconnect from session
2. Try to reconnect to session

What is the expected output? What do you see instead?

The expected output is a successful connection with a window containing my 
desktop.  Instead the client says "Session didn't become ready in time" and 
fails to connect.

What version of the product are you using? On what operating system?

The client is version 3.4.0-10 of the windows client.  The server is on RHEL6 
with nx rpm 3.3.0-38.fc12 installed, and the trunk version of neatx (0.1-1.el6) 
installed.

Please provide any additional information below.

I do not think this is like the other "Session didn't become ready in time" 
message because the nxagent is correctly found, or I would not be able to start 
any session.

These are the details as displayed in the client:

Had a similar problem, if you disconnect the session using the "nx session 
administrator" instead of just closing the window, do you still have the same 
behavior?

When I have had this happen, using NX Client under XP, I notice that there is 
an "NXSSh" process still in my task manager list. Killing it permits connecting 
again.
