Accidental pasting in of %00 after a wikimedia page in Safari (OS X) and possibly other browsers/platforms, causes the URL to extend, in a loop. eg. http://en.wikipedia.org/wiki/Main_Page%00 becomes http://en.wikipedia.org/wiki/wiki/wiki/wiki/wiki/wiki/Main_Page%00 and continues to get longer. I tried this with up-to-date versions of Safari and Firefox, both running on OS X. With Firefox, I got a redirection error, but in Safari the URL physically extended. I am unable to test in other browsers at this time.
I can reproduce a redirect loop error on en.wikipedia under Windows 2000 with Firefox 1.0, but not locally where I have no Apache rewrite rules. IE6-SP1 either has a much larger redirect limit or no limit at all. This URL does not loop: http://en.wikipedia.org/w/index.php?title=Main_Page%00
Using Firefox 1.04, the URL now returns a 404 "Not Found" error. (en.wikipedia.org is currently running MediaWiki 1.4.5.)
with Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7 it returns 404 error: File not found
