Can you please check the exact URLs it's using, and compare against 
your $wgServer and $wgScript settings?

1.3.6 has some extra checks for an Internet Explorer security hole 
where a URL ending in ".txt", ".html" or some other "extension" it 
recognizes is sometimes interpreted as HTML (with arbitrary JavaScript 
execution) instead of according to the set Content-Type header. If a 
raw page request isn't coming from the canonical URL it's thus 
redirected to the canonical URL.

That redirect might perhaps be failing if you have a funky setting. You 
might also try checking the actual headers being sent (use Mozilla and 
install the 'Live HTTP Headers' extension for an easy way to check.)
