Darn! :-)

Not very embarrassing.  It was an early attempt at using nnrss to
read/listen to podcasts.

Actually I can kill those groups.  I don't use them anymore (I use my
squeezeboxen to listen to podcasts at home, and I use rhythmbox to
download and listen to them on mylaptop).

Actually CouchDB is quite comfortable with the JSON generated, as long
as it gets all of it.  See my experiments with feeding that JSON
directly to CouchDB using curl.

Looking at the code you use to send off the http request, ie.
#+begin_src lisp
  ...
  (let ((url-request-method method)
        (url-request-extra-headers headers)
        (url-request-data (if kvdata (json-encode kvdata) nil)))
    (with-current-buffer (url-retrieve-synchronously url)
      ...
#+end_src
the setting of content-length is left to url-retrieve-synchronously, and
it is that code that fails...?

Hm... thoses are ok I think.  But it looks like Adam was right and that
url-retrieve and friends, set content-length from the number of
characters in the data they are trying to send.  And that's actually a
bug in that function, which apparently is present in emacs24 snapshots.
Content-Length should be in bytes.

I guess someone should report it...? :-)
