security-group operations fail with "404 Not Found" errors.

I have a quantum setup with OVS switch plugin. Everything seems to work, except for security-group operations that fail with a 404 error (see below). I am using the ubuntu grizzly packages.

Am I doing something wrong, or doe it have something to do with this: https://lists.launchpad.net/yahoo-eng-team/msg01819.html
