Perhaps I am that user:-) but anyway, I reported the same problem with
MS IE on Japanese Windows to webmaster@brion.inria.fr on March 18 with
the log below.

Although I'm not an expert, the problem apparently seems to be in the
configuration of your apache (or each .htaccess), to which I
unfortunately don't have access...

In any case, the "Language Negotiation Exceptions" section in the
following document might help.
