[Message part 1 (text/plain, inline)]
In further grepping, I discovered that the errors I mentioned:
===
Error: Failure negotiating the session in stage '7'.
Error: Wrong version or invalid session authentication cookie.
===

are listed in the /client-side/ session logs:

===
$ cat ~/.x2go/S-hmangala-55-1381535091_stRgnome-terminal_dp24/sessions 
Loop: PANIC! The remote NX proxy closed the connection.
Loop: PANIC! Failure negotiating the session in stage '7'.
Loop: PANIC! Wrong version or invalid session authentication cookie.
===

but those strings are not found in the client, nor in the server-side nxagent 
shell script so .. where are they coming from..?
