Crash operating through proxy server

Hi All,
This is my first attempt at using Zebedee so please excuse if I have done done
something silly.
I am attempting to set up a VNC tunnel through an M$ ISA Proxy Server.  The
proxy uses per-connection NTLM Authentication.  To get around the
authentication issue I am running the very handy python authentication script
NTLMAPS, which make the proxy appear to connecting apps like it does not use
authentication.
So my connection sequence is

VNC Client -> Zebedee Client -> NTLMAPS -> LAN -> ISA Proxy -> Internet ->
Zebedee Server -> VNC Server

When I attempt to make the connection Zebedee crashes.  This is the log file of
the client at Verbosity 5 (as much as it can log before it crashes).  It's
running in a WinXP SP3 box.

+++++++++++++++++++++++++++

I realise my situation is very complex, but if someone has some suggestions as
to where to start troubleshooting would be most helpful.

I have successfully set up a tunnel & VNC'd between 2 machines within the LAN
just to make sure I have the settings correct for VNC to be talking to both
ends of the tunnel.

It would be good to eliminate NTLMAPS for simplicity.  Has anyone got Zebedee
operating through a proxy that required per-connection authentication?  From my
reading of the documentation it doesn't support that.

PS
   If anyone's wondering I am not doing this without the knowledge of the sys
admin of the proxy.  He doesn't want to open ports for VNC directly for various
reasons, but is OK with this approach provided I can get the connection
authentication operating.
