Comment 42 for bug 978896

Added Jamie directly to the bug.

The difference could come from the fact that you test on top of stable/essex while Jamie tests on top of 2012.1 release. There are 3 extra commits (+ a merge commit) that were backported since April 5: https://github.com/openstack/horizon/commits/stable/essex

That said, it's really not obvious why those extra commits would cause those failures.
