I am trying to setup the following view on CouchDB

{
"_id":"_design/id",
"_rev":"1-9be2e55e05ac368da3047841f301203d",
"language":"javascript",
    "views":{ "by_id":{
              "map" : "function(doc) { emit(doc.id, doc)}"
        },"from_user_id":{
            "map" : "function(doc) { if (doc.from_user_id) {emit(doc.from_user_id, doc)}}"},
        "from_user":{
            "map" : "function(doc) { if (doc.from_user) {emit(doc.from_user, doc)}}"},
        "to_user_id":{
            "map" : "function(doc) {if (doc.to_user_id){ emit(doc.to_user_id, doc)}}"},
        "to_user":{
            "map" : "function(doc) {if (doc.to_user){ emit(doc.to_user, doc)}}" },
        "max_id":{
         "map" : "function(doc) { if (doc.id) {emit(doc._id, eval(doc.id))}}",  
         "reduce" :"function(key,value) { a = value[0]; for (i=1; i <value.length; ++i){a =    Math.max(a,value[i])} return a}"
        }
    }
}

when I try to 'PUT' this using curl:

 curl -X PUT -d keys.json  $CDB/_design/id
 {"error":"bad_request","reason":"invalid UTF-8 JSON"}

I know it's not invalid JSON, because I tested it using the 'json' library built into Python 2.6, it loads fine. JS screw ups give me the error 'must evaluate to a function'

What else might be wrong with it?
