[keystone] How to create a session using trust-scoped token

Hi keystone team,

I met with an issue that can't perform openstack operations using openstack client lib by providing a trust scoped token. However, I can use that token to send HTTP request directly. Here is my code and the error message, http://dpaste.com/1N6AX0R

I asked several times in #openstack-keystone IRC channel, but got no response.
