Visiting logged-out, non-HTTPS shows 503 Service Unavailable (green wm error page)

The history page or other files work fine:

- http://commons.wikimedia.org/wiki/File:Example.svg

It responds with HTTP 200 OK (never 304) and serves a blank page containing only the plain text Headers already sent, terminating.
