I haven't tracked that down. I also have some other bot requesting thousands of those malformed URLs. I can't decide if the bot has misread the HTML source code or there's a fundamental problem in the .htaccess file somewhere. No other UAs exhibit any problem, and there's nothing obvious when manually looking at the HTML source code for any page.
