I was also preparing to post on this subject but my stack trace is different. I am running milestone-proposed versions of Nova and Glance, with the latest Git versions of Dashboard and Keystone. There was another thread on this subject a few weeks ago ( https://lists.launchpad.net/openstack/msg04002.html) and I've confirmed I actually have the fixes mentioned there already in place. Below is my stack trace:

Without going through the code in depth, I am not sure how to simulate the request to nova-api myself in order to provide more detail.
