The missing <Group> tag in Packages/sources.xml causes an error

Hi,

There seems to be an error when <Group> tag is missing and <Source ...> <Arch>..</Arch></Source> exists in Packages/sources.xml.

FYI, here is my Packages/sources.xml.

[[email protected] bcfg2]# cat Packages/sources.xml 
<Sources>
    <Group name="rhel-6.2">
       <Source type="yum" rawurl="ftp://ftp.ussg.indiana.edu/linux/centos/6.2/os/x86_64/"  >
       <Arch>x86_64</Arch>
       </Source>
    </Group>
</Sources>

As soon as bcfg2 -qvn runs without above the <Group> tag, the following error shows up
