[CentOS] CentOS 5.3: duplicate glib2-2.12.3-2.fc6 packages

Hi All,

I have a freshly installed CentOS 5.3, x86_64 system -- just the Base 
package selection (via custom packages selection), and nothing else. 
Immediately after install (no updates), here's what's in the RPM db:

   [root at dev ~]# rpm -qa | grep -i glib2
   glib2-2.12.3-2.fc6
   glib2-2.12.3-2.fc6
   [root at dev ~]#

I have two questions about this:

   (1) Should this package be listed in the RPM database twice?
   (2) Should it be listed there with the fc6 extension?

Any insights would be appreciated.

Thanks,
