Originally reported at #wikimedia-tech by Florian_A:
<Florian_A> the xml-export seems to be broken. if i request two pages, I get the
two pages doubled.
<Florian_A> if i request three pages, I get nine pages, and so on.

I have verified this behavior.

Plus, if we ask for the whole revision of one or two pages, it returns a
mediawiki xml without <page> (expected: error page saying it's disallowed), but
with more i get the full history of the asked pages.

Tested on live Wikipedia.
