I just looked through the error logs and the code a bit more. I think
this passage describes best what seems to happen (though I don't know
why)
So the stracktrace shows that the mochiweb passes the request to
couch_httpd:handle_request where it seems to try to call send_json
(whysoever). It all fails when it tries to encode the binary data as a
json string. This all seems to happen before couch_httpd_external.erl
stuff gets called, which might be able to handle binary data correctly.
Here's the log snippet:
crasher:
initial call: mochiweb_socket_server:acceptor_loop/1
pid: <0.1059.0>
registered_name: []
exception exit: {ucs,{bad_utf8_character_code}}
in function xmerl_ucs:from_utf8/1
in call from mochijson2:json_encode_string/2
in call from mochijson2:'-json_encode_proplist/2-fun-0-'/3
in call from lists:foldl/3
in call from mochijson2:json_encode_proplist/2
in call from couch_httpd:send_json/4
in call from couch_httpd:handle_request/5
in call from mochiweb_http:headers/5
Anyone out that knows more about the internals of couchdb than I do? I
would be grateful for any advice (gotta learn some erlang programming
soonish).

Right now, posting or putting binary data to an external handler
fails,
since the data is parsed as a UTF-8 String and not treated as
binary. The
external handler never gets to do its work, so this might be an
issue
with
the handling of data sent to an external handler. Am I misusing the
external-handler interface?

Lennart,
What version of CouchDB are you on? I seem to remember a patch for
this going into trunk at some point. Not sure if that was pre/post
0.10 though.

Lennart,
Hmm, looking through the svn log I'm not seeing a commit that mentions
body or posts. I swear I remember something like that coming through
at one point. Benoit, didn't you have something to do with that?
