Python App Engine Queue Tasks

I'm trying to run a task on app engine, but i'm getting the following error:

ERROR    2012-07-24 18:47:01,030 wsgi.py:189] 
Traceback (most recent call last):
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/runtime/wsgi.py", line 187, in Handle
    handler = _config_handle.add_wsgi_middleware(self._LoadHandler())
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/runtime/wsgi.py", line 225, in _LoadHandler
    handler = __import__(path[0])
ImportError: No module named tasks
INFO     2012-07-24 18:47:01,040 dev_appserver.py:2952] "POST /tasks HTTP/1.1" 500 -
WARNING  2012-07-24 18:47:01,045 taskqueue_stub.py:1934] Task task22 failed to execute. This task will retry in 0.100 seconds

I'm doing this to add the task:

import os
import webapp2
from google.appengine.ext.webapp import blobstore_handlers
from controllers.basehandler import BaseHandler
from google.appengine.ext import blobstore
from google.appengine.api import taskqueue
from google.appengine.ext.webapp.util import run_wsgi_app


class UploadHandler(blobstore_handlers.BlobstoreUploadHandler, BaseHandler):
    def post(self):
        upload_files = self.get_uploads('video_file')
        blob_info = upload_files[0]

        current_user = self.current_user

        if current_user:
            if current_user.video_file_bob:
                old_video = current_user.video_file_bob.key()
                blobstore.delete(old_video)

            current_user.video_file_bob = blob_info.key()
            current_user.put()

            params = {'user':current_user}

            taskqueue.add(url='/tasks')

        self.redirect('/video_upload')

app = webapp2.WSGIApplication([('/store_video', UploadHandler)],
                                     debug=True)

and this is the code for the task:

import re
import urlparse
import webapp2
from google.appengine.ext import blobstore
from controllers.basehandler import BaseHandler
import gdata.youtube.service
from google.appengine.api import taskqueue
from google.appengine.ext.webapp.util import run_wsgi_app
import logging


class YoutubeUpload(BaseHandler):

    def post(self):
        logging.info('Here')


app = webapp2.WSGIApplication([('/tasks', YoutubeUpload)],
                                 debug=True)

any ideas on how to solve this?

EDIT

application: traapp
version: 1
runtime: python27
api_version: 1
threadsafe: True

handlers:
- url: /images
  static_dir: assets/images

It looks like an import error "ImportError: No module named tasks". So I would think that the following would be incorrect. 

- url: /tasks
  script: tasks.youtube_upload.app

What is the path and filename of the second block in your question? The way you have it setup now, you would need to have youtube_upload.app in a /tasks folder that had an init.py in it as well.
