CentOS - Jul 2012 - [CentOS 6.3] rsyslog 5.8.10-2 - PreserveFQDN directive ignored

Hello,

I recently upgraded a server from CentOS 6.2 to 6.3
I found a change in the behavior of rsyslog's configuration file that
I found particularly interesting.
The "$PreserveFQDN on" directive was not being recognized as the
config remained unchanged during the upgrade.  This incorrect behavior
caused the host to syslog with only the host name and not it's fully
qualified domain name.

** Has anyone else experienced this odd behavior? **

I did find a workaround [0] [1], but feel this behavior is a bug.
Note the bugreport linked previously was for version 5.4.0 and
reported in July 2010.
If I make $PreserveFQDN the _first_ directive it syslogs with the FQDN
otherwise the directive is ignored.

The official 6.2 mirror has rsyslog-4.6.2-12.el6.i686.rpm and 6.3 has
rsyslog-5.8.10-2.el6.i686.rpm

For the record here's my output from `yum info rsyslog`:

Description : Rsyslog is an enhanced, multi-threaded syslog daemon. It
supports MySQL,
            : syslog/TCP, RFC 3195, permitted sender lists, filtering
on any message part,
            : and fine grain output format control. It is compatible
with stock sysklogd
            : and can be used as a drop-in replacement. Rsyslog is
simple to set up, with
            : advanced features suitable for enterprise-class,
encryption-protected syslog
            : relay chains.

I've not found other reports of this issue with CentOS 6.3 so far and
there's no recent mention of this bug [yet] on the Rsyslog Bugzilla
[2].
But the following ticket [3] submitted this past April makes me wonder.
