Comment 2 RHEL Program Management 2011-03-28 09:17:44 UTC 
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
in the current release, Red Hat is unfortunately unable to
address this request at this time. Red Hat invites you to
ask your support representative to propose this request, if
appropriate and relevant, in the next release of Red Hat
Enterprise Linux. If you would like it considered as an
exception in the current release, please ask your support
representative.
Comment 3 Petr Pisar 2014-10-21 11:37:14 UTC 
Porting the fix is very difficult. Because nobody complained so far, I will postpone fixing this bug.
