Looks like you merged part of this patch (the last hunk) in r965667

>                 URL:
>             Project: CouchDB
>          Issue Type: Bug
>          Components: Database Core
>    Affects Versions: 1.0
>         Environment: Erlang/OTP R13B04
>            Reporter: Jason Smith

> CouchDB prevents the new view server handler methods, _show, _update, etc. from handling
unknown HTTP methods. This prevents Couch apps from being able to implement extensions to
the HTTP specification or to add application-specific methods to HTTP, violating the spirit
of _show and _update.
> For example, it is not possible to make a CouchApp WebDAV server because _show and _list
must support the PROPFIND method.
> In couch_httpd:handle_request_int/5, the response from Mochi is coerced to an atom if
and only if the atom already exists (using couch_util:to_existing_atom/1). That is an odd
whitelist, to say the least:
>     $ curl localhost:5984 -X PROPFIND # Crashes mochiweb when to_existing_atom throws
>     curl: (52) Empty reply from server
>     $ curl localhost:5984 -X list_to_binary # Any atom works
>     {"error":"method_not_allowed","reason":"Only GET,HEAD allowed"}
> Considering the cURL commands above, I filed this as a bug, not a feature. I will explore
some options and submit patches.
