---------------------------------------------

             Summary: list function + no rows return 500
                 Key: COUCHDB-2847
                 URL: https://issues.apache.org/jira/browse/COUCHDB-2847
             Project: CouchDB
          Issue Type: Bug
      Security Level: public (Regular issues)
            Reporter: James Mark Mackenzie


A list function applied to a view with no rows returned results in a 500 response from the server. 

Steps to reproduce: 
1) PUT /db
2) PUT /db/_design/ddoc
3) GET /db/ddoc/_list/simple_row_render/list_animal_ids

The system reponeds with: 
{u'reason': u'undef', u'ref': 902602498, u'error': u'unknown_error'}

Ddoc: 
{noformat}
{"_id": "_design/ddoc",
               "views": {"list_animal_ids": {"map": "function(doc) {if(doc._id){emit(doc._id, null);}}"}},
               "lists": {"simple_row_render": "function(head, req) {var row; while(row=getRow()) {send(JSON.stringify(row)); }}"}}
{noformat}
