There's a whole bunch of similar reports at
. Looks like a Squid bug.
If the cached version of a page is invalid, like not having the
Content-Encoding header even though the content is gzipped, then that's
the message people get. I've seen it a couple of times too, most often
when loading my watchlist, but it's obviously more common for
unregistered users since they get cached versions of articles and a
single invalid version lives on.
It happens regardless of the browser or its configuration, so I don't
think there's any more information users can provide about the problem,
unless there's a configuration that manages to get the invalid version
there in the first place. When an unregistered user gets it, it can be
reproduced elsewhere until the page is purged, but other than the squid
server number and missing encoding header, there's not much information
there. By the time someone could look at an individual case from the
squids, it'll be purged.
It's probably also not as common as some people emailing Wikipedia make
it seem to be. They get it repeatedly from the same page because the
invalid version is still in their cache. Giving a slightly different url
to access the page may often be easier than trying to explain how to
clear the remote and local cache.
