[Seaside] RFB client-server issues in seaside 3.0.6

I have not looked at this in months, but here goes....

If I start a VNC Server (really its an RFB session) on Pharo2.0 I am able to connect to that server with the squeak client.

I am unable to connect to a Squeak Server with either the Pharo client or the Squeak client.

The pharo client barfs at requestHostAndDisplay: promptString  on the 'withblankstrimmed' message send to a bytstring 'localhost'.

The squeak client does not throw a debugger, but Transcript output shows the following:

RFB: [RFBServer>>runSession:] connection from localhost
RFB: [RFBSession>>initServer:socket:reverse:] initialised
RFB: [RFBSession>>start] started a Process in [] in BlockClosure>>newProcess
RFB: [RFBSession>>runLoop] running
RFB: [RFBSession>>runLoop] send protocol version
[RFBClient>>rfbProtocolVersion] server version 3.7

RFB: caught Error: vmParameterAt:put: failed
RFB: [RFBSession>>updateLoop] update loop exiting
RFB: caught ConnectionClosed: Connection close while waiting for data.
RFB: [RFBSession>>runLoop] run loop exiting
RFB: [RFBSession>>release] released
[RFBClient>>rfbProtocolVersion] viewer version 3.7
RFB: caught ConnectionClosed: Connection close while waiting for data.
 To get to this stage, I had to do some trivial replaces of underscore assignments to :=

Looking at my Monticello from back then, I was using RFB.ikp.6

Hope that helps.

What were the issues you had with RFB on Squeak?
