On last version 1.3.1 mapreduce return strange results {ok,[]} #72

After update from 1.2 I cannot get simple map reduce
That code works fine on 1.2:
riakc_pb_socket:mapred(Pid, [{Bucket, Key}],
                                       [{map, {modfun, riak_kv_mapreduce, map_object_value},undefined, true}])
and return {ok,[{0,Result}]} on success. Now I get {ok,[]} on same code. All buckets and keys reference to real entities


@mkuznetsov I'll try to take a look some time this week. I'm surprised as the the mapred code hasn't really changed since riakc 1.2.

all the M/R unit tests for 1.3.1 pass:

riakc_pb_socket:2217: live_node_tests (map reduce bad query)...[0.001 s] ok

Which version of Riak?
JavaScript or Erlang M/R query?
Can you send provide any code that will make mapred/* fail?


Closing as stale.
