Ok, that new cinder.conf.sample is showing changes caused by these
oslo.messaging changes:

  https://review.openstack.org/101583
  https://review.openstack.org/99291

Both of those changes were first released in 1.4.0.0a1 which is an alpha
version targeting Juno and are not available in the 1.3.0 Icehouse
version - i.e. 1.4.0.0a1 should not be used with stable/icehouse Cinder.

It seems 1.3.0 *is* being used:

    2014-06-29 19:17:50.154 | oslo.messaging==1.3.0

and the output is just confusing:

  ...

i.e. it's showing that the file you proposed was generated with
1.4.0.0a1 and the file generated during the test job was generated with
1.3.0. Which is what I'd expect - the update you proposed is not
appropriate for stable/icehouse.

So why is the py27 job passing?

  2014-06-29 19:21:12.875 | oslo.messaging==1.4.0.0a2

That's the problem right there - 1.4.0.0a2 should not be getting
installed on the stable/icehouse branch. I'm not sure why it is. Someone
on #openstack-infra could probably help figure it out.

Thanks,
