Here's the *really* odd thing about this bug (and probably bug 765607): It was sent by developer.mozilla.org - and *not* developer-new.mozilla.org

Even though "kumawiki" was set to disallow access to anyone but superusers, it was somehow letting some people in from search engines. I just deleted the kumawiki flag altogether, and the 500 ISE turned into a 404.

So...

1) I don't know why waffle seemed to be letting people in through to kuma, and

2) I don't know how people are getting links to kuma on developer.mozilla.org

Duping this in favor of bug 766003. I think the reason this error has come up is that the "kumawiki" waffle flag is not working right. How people got to this URL, I don't know, but it should have been a 404
