YUM Problem

[Daryll Strauss <daryll strauss gmail com>]

As of a couple days ago yum stopped working. The traceback ends with:
  File "/usr/lib/python2.5/site-packages/urlgrabber/grabber.py", line 
695, in process_http
    auth_handler.add_password(None, host, user, password)
UnboundLocalError: local variable 'user' referenced before assignment

I added an extra print statement. The "parts" being passed in to the 
routine were:
Parts:  ('http', 'download  DISTNAME@.redhat.com', 
'/pub/fedora/linux/core/7/i386/os/repodata/repomd.xml', '', '', '')

It looks like the @DISTNAME@ is causing the problem. The routine thinks 
we're specifying a user name instead of expanding a meta variable.

I installed F7T4 and have been tracking rawhide. Am I missing something? 
Any suggestions on how to fix it?
