answer sort broken

edit

Sorting answers by "oldest" or "newest" seems to be broken. For example, try it on the robot logo question. The problem, it seems, is that the link

http://askbot.org/en/question/15/?sort=latest#sort-top

redirects to

http://askbot.org/en/question/15/any-ideas-for-the-funny-robot-logo-design#sort-top

instead of

http://askbot.org/en/question/15/any-ideas-for-the-funny-robot-logo-design?sort=latest#sort-top

(which does work as it should)
