Comment 1 for bug 1365046

A bit more triage shows http://logs.openstack.org/54/109754/13/check/check-tempest-dsvm-full/10d7fe8/logs/devstack-gate-setup-workspace-new.txt.gz#_2014-09-03_08_50_25_414. Looks like git hit a TLS error fetching nova refs from the git mirrors. This made workspace setup short circuit and fail without cloning and updating devstack.
