Unable to start session:

[GoogleCodeExporter]

What steps will reproduce the problem?
1.  Installed neatx-r59 from SVN, NXAgent 3.4.0 from sources. Connecting with 
NXClient 3.4.0
2.  Attempt connection to a VM running neatx
3.  Successful access to NX, but when the VM was terminated through libvirt the 
following happens:
Session is created properly in "sessions" folder, but NXClient gets the error 
"Session XXXX has status "terminated", aborting" and the server's 
/var/log/messages says "nxnode[1936]: ERROR agent:376 Agent error: Aborting 
session with 'Cannot establish any listening sockets - Make sure an X server 
isn't already running'.  There is no X server running, nor GDM, etc.
