json_xs didn't complain, but I've found that notmuch outputs
  Failed to verify signed part: Cannot verify multipart/signed part: unsupported signature protocol 'application/x-pkcs7-signature'.
to stderr before the json output and emacs tries to parse
stderr. Emacs then complains about not finding "F" in json-readtable.

The following patch fixes the problem for me, but I do not know if it is
a good thing to throw away the stderr output of notmuch.
