Description

Whenever a view emits an array containing undefined as a key an Erlang is thrown:

For example, if there's at least one document in the db without foo being set, the following view

function(doc) {
emit([doc.foo], doc);
}

triggers

nocatch,{bad_value,"Cannot encode 'undefined' value as JSON",
[

{couch_query_servers,prompt,2}

,

{couch_query_servers,'-map_docs/2-fun-0-',2}

,

{lists,map,2}

,

{couch_query_servers,map_docs,2}

,

{couch_view,view_compute,2}

,

{couch_view,update_group,1}

,

{couch_view,temp_update_loop,2}

]}

OTOH,

function(doc) {
emit(doc.foo, doc);
}

causes no problems.
