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?
