I reproduced the failure and I can confirm I have no authorized_keys file in the failing instance.
To reproduce the failure it is sufficient to start an instance with 4 cores and 8GB of memory, launch devstack with a localrc very similar to that of the full neutron test, and then keep running scenario tests.

A tweak for not removing the instance where ssh fails helps a lot: http:// paste.openstack .org/show/ 105982/
