I don't know what to advise for Platform, sorry.

I've attached a copy of the article (which is an interesting read :-)).
 Still can't reproduce the problem, but I don't use XEmacs with Windows.
 I've put on my list to try with no-Gnus final, but I have no idea how
long it'll be before I get to it.  You might want to ask on xemacs-beta,
to get more eyes looking at this.

When I first view the article, it's in raw HTML.  Did you do any washing
on the article before the crash?
