Description of problem:
up2date when running from a yum mirror - planetmirror in australia in particular
(not sure if it happens elsewhere) fails to get the noarch packages such as
caching-nameserver but instead just hangs. in the console from which up2date is
run there's a python/http error 404 stating the file is not found, yet when
browsing to the repository the file is indead there. up2date just hangs and
doesn't deal with the error. The files can be downloaded with manually with
ftp/http and installed with no problem. Errors included below.

yum rawhide http://public.www.planetmirror.com.au/pub/redhat/redhat-rawhide/
