Description of problem:
Installing todays rawhide as a xen guest, fedora produces a anaconda.repo that
halts yum

Version-Release number of selected component (if applicable):
10.91.14-1 (not 100% sure of this)
yum-2.5.1-4

How reproducible:
every time yum runs, havent't tried reinstalling yet 

Steps to Reproduce:
1. install rawhide as of today
2. yum upgrade or yum update
3.
  
Actual results:
# yum upgrade
Options Error: Error parsing 'gpgkey': URL must be http, ftp, file or https not ""

[..]

Expected results:
yum should pull in upgrades

Additional info:
--disablerepo=anaconda does not work, have to move the file out of it's way.
When commenting out gpgkey, it complains about mirrorlist that has 'None' as a
value - and then goes on complaining about the others with 'None'

I'm attaching the anaconda.repo
