Get a harmless error everytime a document is created in couchdb using python-cloudant

[Ramanadham, Radhika]

HI,
I am using cloudant0.5.8 and python3.3, couchdb 1.5.1 on suse linux. 
I get the error whenever I create a document. The document does get created, 
but I can't avoid the error.


Exception TypeError: TypeError('delete() takes 2 positional arguments but 3 
were given',) in <bound method Design.__del__ of <cloudant.design.Design object 
at 0x7f265f4f4dd0>> ignored

Here is my code where I create a design document-

def createDesignDocForErrors():
    design = db.design(errors_view)
    resp = design.put(params={
        "_id":"_design/errors",
        "language": "javascript",
        "views":
        {
            "by_test_id": {
                #"map": "function(doc) { if (doc.type == 'error')  
emit(doc.test_id, doc.errors) }"
                "map": "function(doc) { if (doc.type == 'error')  
emit(doc.test_id, doc.error_count) }",
                "reduce" : "_sum"
            },

            
#http://<IP>:5984/longevity/_design/errors/_view/by_testid_starttime?group=true
            "by_testid_starttime": {
                "map": "function(doc) { if (doc.type == 'error')  
emit([doc.test_id,doc.start_time], doc.error_count) }",
                "reduce" : "function(keys, values) {return (values[0])}"
            }
        }
     })

Can anyone help?

Thanks,
Radhika
