If you're not sure about what you say then don't mess with the users. This was one of
most frequently asked questions a few months ago and I don't want to start answering
the same question every day.
ssh -Y is fine for all daily usage. If you know what you're dooing then use -X. But don't
bother the mailinglist with strange errors which did not occur before.

Live with it. It's just a warning.
If it really bothers you then setup xauth.
man Xsecurity will give you a quite detailed introduction to the whole X11 authentication
schemes. But this is a quite complex task. There have been some threads on the mailing list
about this topic (search for md5sum and xauth).
