I'm seeing exactly the same problem on FC4.  I just put up another post 
about it.  I had at that time only tried to connect using older versions 
of the VNC viewer on various systems (Windows, my Kubuntu laptop).  But 
I just tried connecting to a vncserver using the same version of 
vncviewer (vnc-4.1.1-10.1.fc4) and get the same error message.  
Something's broken here.
