Swift CLI can't access to keystone with self signed certification

OS ver. Ubuntu 12.04.1 LTS
python-swiftclient 1:1.2.0-0ubuntu2~cloud0
python-keystoneclient 1:0.1.3-0ubuntu1~cloud0

I am building a swift cluster with keystone using CloudArchive and
having a trouble on keystone auth with self signed certification.

I built a keystone server with ssl reverse proxy by apache.
The SSL certification is self-signed one.
When I tried to access swift server via swift CLI, an error happened as follows.

>swift -V 2 -A https://b1auth/v2.0 -U demo:demo -K XXXXX stat

Traceback (most recent call last):
  File "/usr/bin/swift", line 1190, in <module>
    error_queue)

    headers = conn.head_account()

    return self._retry(None, head_account)

When I accessed to keystone directly without SSL as follows, swift CLI worked well.

>swift -V 2 -A http://b1auth:5000/v2.0 -U demo:demo -K XXXXX stat

   Account: AUTH_xxxxxxxxxxxxxxxxxxxxxxxx

I guess that the cause is swift CLI doesn't support --insecure option.
As a trial, I modified swiftclient/client.py as follows.
In this case CLI worked well.
