OpenSSH and Xauth

I have tumpled over quite a big problem on my machine. I'm running
Debian Potato with OpenSSH-1.2.3 protocol 1.5 installed from the
debian packages. When I ssh from any computer (including my own) then
I can't get any programs to display X. I have turned ForwardAgent and
ForwardX11 on in my ssh_config. When I turn on debugging this is what
I get:

17:14 simpsons at lada% ssh -v bart.aalk                                         ~
SSH Version 1.2.26 [sparc-sun-solaris2.6], protocol version 1.5.

lada: Requesting shell.

Last login: Tue Apr 25 16:48:44 2000 from bart on pts/6

But when trying to execute any X program I get this:
17:15 simpsons at bart% xlogo                                                    ~

Rejected connection at Tue Apr 25 17:15:34 2000: X11 connection from bart port 1169

lada: Channel 0 closes incoming data stream.
lada: Channel 0 closes outgoing data stream.
lada: Channel 0 sends oclosed.
lada: Channel 0 sends ieof.
lada: Channel 0 receives input eof.
lada: X problem fix: close the other direction.
lada: Channel 0 receives output closed.
lada: Channel 0 terminates.
X connection to bart:10.0 broken (explicit kill or server shutdown).

And this is something I don't understand!

I use exactly the same version of Openssh on another machine which is
also a debian machine without any problems. The only difference in
these two, are that the one I'm having problems with is running Xfree
4.0 and the other is running Xfree 3.3.6, otherwise they are
practically identical!

Someone please help....
