I think the CHANGELOG narrows down the search and it is what was identified earlier:

2-19-2002 - get() now emits mimetype, fixes problem with konqi not downloading
file for
            viewing in kpart.
          - get port number using getservbyname instead of hard coding it.

So it is the 'getservbyname' call that is relied upon to get the port
information -- and I'll bet the fix is just what we talked about above. Now how
to figure out how to make the pieces of 'getservbyname' return the port
correctly again from the ssh output?
