Websites consistently failing

["Nolan J. Darilek" <nolan@xxxxxxxxxxxxxxxx>]

There are certain websites (everything in the axkit wiki,
http://www.axkit.org/wiki/view/AxKit/LiveSites for instance) which I
can't visit using emacs-w3m 1.3.6 without receiving the following
error:

Reading http://www.axkit.org/wiki/view/AxKit/LiveSites...done
Can't decode encoded contents: http://www.axkit.org/wiki/view/AxKit/LiveSites
Cannot retrieve URL: http://www.axkit.org/wiki/view/AxKit/LiveSites (exit status: 0)

This also happens on several "normal" websites after a time; I'll get
the above error on a site which, only a few moments earlier, worked
fine and, until I kill and restart my emacs session, the site refuses
to load. This is under w3m 0.4.1 and emacs 21.3 if that matters at
all.

Any ideas about what might be happening?
