Fun with GAE: urlfetch rpc time out

Question

I'm trying to write an image to the blob store. I've tried fetch_response = urlfetch.fetch(image_url, deadline=10) which timed out and now I'm trying rpc with the same result. Can someone tell me what's wrong with the following code? Thanks for your help:

    media_items = ['logo.png']
    content_type = 'image/png'
    for media_item in media_items:
        image_url = 'http://localhost:8080/image/' + media_item
        #fetch_response = urlfetch.fetch(image_url, deadline=10)
        rpc = urlfetch.create_rpc(deadline=20)
        urlfetch.make_fetch_call(rpc, image_url)
        try:
            file_data = rpc.get_result()
            file_name = files.blobstore.create(mime_type=content_type)
            with files.open(file_name, 'a') as f:
                f.write(file_data)
            files.finalize(file_name)
            blob_key = files.blobstore.get_blob_key(file_name)
            create_media_item(blob_key)
        except urlfetch.DownloadError:
            logging.error('DownloadError')

This is running on my machine and if I look at the picture in the browser using this URL it displays. My logging.error() is printed.

Use `logging.exception` instead of `logging.error`, and your log message will include the stacktrace and exception information. — Nick Johnson, Jul 26 '11 at 01:56

If you are fetching the blob from your own application, you should probably use BlobReader or load the file from the file system.

As it seems the dev server is single threaded and you have to run 2 instaces if you want to send requests to it:
