Bug 918948 requests a rebase to nss-3.4.3 and that version in turns requires nspr-4.9.5
I guess this bug needs the rhel-5.9.z+ flag, the same as seen in bug 918948 ?
Closing as CLOSED/ERRATA as the fix is being delivered as part of errata https://errata.devel.redhat.com/errata/brewfiles.cgi?id=14819 (see Comment #8).
