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.
Since RHEL-5 is now in production phase 2 (only important/critical bugs are fixed) and this is not important issue, I'm closing this bug. Please consider to upgrade to RHEL-6 which has this bug fixed.
