Google App Engine，云存储无法读取python中的上传文件

Question

I created the bucket, upload a file via

 gsutil cp -a public-read test.htm gs://BUCKETNAME

I can see the file in the Storage Browser and with gsutil ls

When I try to read it with the following code, I get

NotFoundError: Expect status [200] from Google Storage. But got status 404.

Code:

import logging
import os
import lib.cloudstorage as gcs
import webapp2

from google.appengine.api import app_identity


my_default_retry_params = gcs.RetryParams(initial_delay=0.2,
                                          max_delay=5.0,
                                          backoff_factor=2,
                                          max_retry_period=50)
gcs.set_default_retry_params(my_default_retry_params)

class MainPage(webapp2.RequestHandler):

    def get(self):
        bucket_name = os.environ.get('BUCKET_NAME',
        app_identity.get_default_gcs_bucket_name())

        self.response.headers['Content-Type'] = 'text/plain'
        self.response.write('Demo GCS Application running from Version: '
           + os.environ['CURRENT_VERSION_ID'] + '\n')
        self.response.write('Using bucket name: ' + bucket_name + '\n\n')

        bucket = '/' + bucket_name
        filename = bucket + '/test.htm'
        self.read_file(filename)


    def read_file(self, filename):
        self.response.write('Abbreviated file content (first line and last 1K):\n')

        gcs_file = gcs.open(filename)
        self.response.write(gcs_file)

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

Strage thing happens, when I use the sample code from here ( https://github.com/GoogleCloudPlatform/appengine-gcs-client/blob/master/python/demo/main.py ) in my environment.

The code creates and writes a file on the same bucket, then reads it and deletes it. Works fine, but when I comment out the delete parts, I can not see the files in Storage Browser or with gsutil, but I can still read them with the code.

I checked my bucket permissions in Storage Browser and they seem fine, the service account of the app is bucket owner.

Any help is greatly appreciated.

After revisiting this, due to recent demand I figured it out. gsutil has a bug, I read about its somewhere at github. When I upload the file via storage browser or the python client libraries it works.
