F12 updates broken today?

[Marcus D. Leech]

I'm getting this message on a freshly-installed-from-live-cd system for 
F12 today:

Error Type:<class 'yum.Errors.RepoError'>
Error Value: Error getting repository data for installed, repository not
found
    File : /usr/share/PackageKit/helpers/yum/yumBackend.py, line 3125, in

      main()

      backend.dispatcher(sys.argv[1:])
    File : /usr/lib/python2.6/site-packages/packagekit/backend.py, line

      signed = self._is_package_repo_signed(pkg)
    File : /usr/share/PackageKit/helpers/yum/yumBackend.py, line 1437, in
_is_package_repo_signed
      repo = self.yumbase.repos.getRepo(pkg.repoid)
    File : /usr/lib/python2.6/site-packages/yum/repos.py, line 121, in
getRepo
      'Error getting repository data for $s, repository not found' $ (repoid)

The system appears to be reasonably sane, so it only appears to be updates that are broken.  Which is kinda
   broken, if you ask me :-)
