Can you please test http://brewweb.devel.redhat.com/brew/taskinfo?taskID=7444793 as a fix? (see comment 17 on bug 1076728)
Robert, can you reply on https://bugzilla.redhat.com/show_bug.cgi?id=1088390#c14?
David, I think that since the Z-Stream/errata solves this and it's fixed in 6.5 this should be fine to close this out. Thank you guys for your help!
