As rbarlow suggested, I highly suspect this is a duplicate of https://pulp.plan.io/issues/1711. Have you tried with our most recent beta (0.8 I think)? Please try it since the upstream bug will very likely be closed on Friday at triage as a duplicate.
I agree that issue #1756 is a duplicate of #1711.
Tested upstream pulp-selinux-2.8.0-0.8.beta.el6.noarch.rpm without any selinux denials.
The Pulp upstream bug status is at ON_QA. Updating the external tracker on this bug.
Moving to POST, since fix is available upstream.
The Pulp upstream bug status is at CLOSED - CURRENTRELEASE. Updating the external tracker on this bug.
