AttributeError: url on Storage Exception when key not found

When attempting to get a key that does not exist the exception for the NotFoundError is trying to reference request.url which does not exist.

Traceback (most recent call last):
  [...]
    file_key = self.bucket.get_key(path)
  File "gcloud/storage/bucket.py", line 83, in get_key
    response = self.connection.api_request(method='GET', path=key.path)
  File "gcloud/storage/connection.py", line 212, in api_request
    raise exceptions.NotFoundError(response, content)

    self.message = 'GET %s returned a 404.' % (response.url)

AttributeError: url

Thanks for this report. I'm having a look.

Don't assume that httplib2 responses contain any preset attributes, s…

It is actually a httplib2.Response instance, which is a dict with some dynamically looked up attributes. We can't guarantee it contains a name. Likely we should print the whole dict instead of trying to look up the url.
