Hello everyone,

As discussed with Michael on IRC we have found the issue to be with
the duplicate repo lines.  My kickstart template for cobbler currently
has the following line

$yum_repo_stanza

Which was producing this

repo --name=source-1
--baseurl=http://10.107.1.111/cobbler/ks_mirror/redhat-5.1-x86_64/VT
repo --name=source-2
--baseurl=http://10.107.1.111/cobbler/ks_mirror/redhat-5.1-x86_64/ClusterStorage
repo --name=source-3
--baseurl=http://10.107.1.111/cobbler/ks_mirror/redhat-5.1-x86_64/Cluster
repo --name=source-4
--baseurl=http://10.107.1.111/cobbler/ks_mirror/redhat-5.1-x86_64/Server
repo --name=source-5
--baseurl=http://10.107.1.111/cobbler/ks_mirror/redhat-5.1-x86_64/VT
repo --name=source-6
--baseurl=http://10.107.1.111/cobbler/ks_mirror/redhat-5.1-x86_64/ClusterStorage
repo --name=source-7
--baseurl=http://10.107.1.111/cobbler/ks_mirror/redhat-5.1-x86_64/Cluster
repo --name=source-8
--baseurl=http://10.107.1.111/cobbler/ks_mirror/redhat-5.1-x86_64/Server

So due to the duplication above anaconda was failing and producing the
traceback in the original email.  Removing the duplicates and manually
adding this to the kickstart fixed the issue.

repo --name=source-1
--baseurl=http://10.107.1.111/cobbler/ks_mirror/redhat-5.1-x86_64/VT
repo --name=source-2
--baseurl=http://10.107.1.111/cobbler/ks_mirror/redhat-5.1-x86_64/ClusterStorage
repo --name=source-3
--baseurl=http://10.107.1.111/cobbler/ks_mirror/redhat-5.1-x86_64/Cluster
repo --name=source-4
--baseurl=http://10.107.1.111/cobbler/ks_mirror/redhat-5.1-x86_64/Server

I hope this post helps anyone with a similar issue.

Thanks again for the help everyone, take care.
