Appengine BulkLoader problem using development server

I am doing something that should be simple and getting stuck over and over again. I am getting this error when uploading quite simple csv files to my development server:

Error in WorkerThread-0: app "dev~fbdec" cannot access app "fbdec"'s data

The exact output being:

This is the app.yaml file:

application: fbdec
version: 1
runtime: python
api_version: 1

handlers:
- url: /static
  static_dir: static

- url: /remote_api
  script: $PYTHON_LIB/google/appengine/ext/remote_api/handler.py
  login: admin

- url: /.*
  script: fbdec.py

This the shell call to perform the upload:

appcfg.py upload_data --config_file=fbdec/fbuploader.py --filename=cols.csv --kind=Cols --has_header --num_threads=1 --url=http://localhost:8080/remote_api fbdec/

This is the uploader code:

import cgi
import datetime
import logging
import os

import datetime
from google.appengine.ext import db
from google.appengine.tools import bulkloader
from os import environ


class Grobs(db.Model):
    coleccion = db.TextProperty()
    objeto= db.TextProperty() 
    descripcion = db.TextProperty()

class GrobLoader(bulkloader.Loader):
    def __init__(self):
        bulkloader.Loader.__init__(self, 'Grobs',
                                   [('coleccion', str),  
                                    ('objeto', str),
                                    ('descripcion', str)
                                   ])

class Cols(db.Model):
    coleccion = db.TextProperty()
    descripcion= db.TextProperty() 

class ColLoader(bulkloader.Loader):
    def __init__(self):
        bulkloader.Loader.__init__(self, 'Cols',
                                   [('coleccion', str),
                                    ('descripcion', str)
                                   ])

loaders = [GrobLoader, ColLoader]

And this the cols.csv file:

coleccion,descripcion
gafas,descripcion
sombreros,descripcion

Any help will be really welcome. I cant figure out what I am doing wrong.

I am using Appengine 1.5.2 on Mac Osx Leopard. I have tried both both python 2.5.4 and 2.6.6 (just in case).

Thanks in advance and best regards !

When starting dev_appserver, pass the --default_partition="" parameter.

On newer SDK, use the --application=dev~your-app option.

I recently had the same problem, hence I created a script to do this:

APP=$1 #your app name
IN=$2 #the file containing the data to upload
DIR=$3 #the folder containing your app.yaml
appcfg.py upload_data --email=foobar@nowhere.com --passin --application=dev~$APP --filename=$IN --url=http://localhost:8080/_ah/remote_api $DIR -v
