I'm seeing the same problem with the same XEmacs, also on Kubuntu
(5.10). It seems that open-network-stream won't work with a number as
a port argument.

As a work-around you can add the following function to your slime.el
and replace the 2 calls to open-network-stream with
my-open-network-stream:
(defun my-open-network-stream (name buffer host port)
  (open-network-stream name buffer host (if (numberp port)
(number-to-string port) port) 'tcp))

When you google around a bit it seems that there was indeed a problem
with open-network-stream in that XEmacs version.
