CentOS - Dec 2013 - md5sum mismatch between CentOS 6.4 and 6.5 repository

Hello,

when I download python-slip-dbus-0.2.20-1.el6_2.noarch.rpm from CentOS 6.5
repository the md5sum is different than when I download same file from 6.4.

wget http://msync.centos.org/centos-6/6.5/os/x86_64/Packages/
     python-slip-dbus-0.2.20-1.el6_2.noarch.rpm
     -O python-slip-dbus-0.2.20-1.el6_2.noarch.rpm.65
wget http://msync.centos.org/centos-6/6.4/os/x86_64/Packages/
     python-slip-dbus-0.2.20-1.el6_2.noarch.rpm
     -O python-slip-dbus-0.2.20-1.el6_2.noarch.rpm.64

ls -l
..... 30844 Mar 26  2012 python-slip-dbus-0.2.20-1.el6_2.noarch.rpm.64
..... 30844 Mar 26  2012 python-slip-dbus-0.2.20-1.el6_2.noarch.rpm.65

md5sum python-slip-dbus-0.2.20-1.el6_2.noarch.rpm.*
20bb02e6f3b7b71e09dcaff7f3b0ca02  python-slip-dbus-0.2.20-1.el6_2.noarch.rpm.64
d37fe4404a7a5fdb27b29f9b5ed09c73  python-slip-dbus-0.2.20-1.el6_2.noarch.rpm.65

Any comments?

Background:
We have a local CentOS mirror and after updating to 6.5 the kickstart
installation fails because of the wrong md5sum of python-slip-dbus. We mirror
with rsync (no -c) and so we had the version from 6.4 in our 6.5 repository.

(Same seams to be true for python-paste-script-1.7.3-5.el6_3.noarch.rpm and
slf4j-javadoc-1.5.8-8.el6.noarch.rpm)

Best regards,
Ralf

 Something got mixed up somewhere. The first one (md5 20bb...) is from the
x86_64
 branch, both 6.4 and 6.5, and the second one (md5 d37f...) is from the i386
 branch, also 6.4 and 6.5.
