Hi Filipe, I ran into a possible issue replicating from BC 0.4 to CouchDB 1.2.x (someone needs to verify this is a problem and not my local setup).
The issue seems to be the treatment of sequence numbers like [2,<<"foo">>]. The latest in 1.2.x of couch_replicator_httpc:send_req runs ?b2l(iolist_to_binary(...)) over that seq and eventually full_url trundles on down to mochiweb_util:quote_plus which loses the brackets and converts the 2 to a %02 I can get around this [1] by converting [2,<<"foo">>] to "2-foo" which is the old format, but this is clearly a workaround. Perhaps this should be fixed in mochiweb_util ? As an aside I noticed mochiweb_util:urlencode does exactly what you have in query_to_str_args so those funs can probably go away.
