I had the same problem as well, however rather than cleaning all I only
deleted the repo metadata files in /var/cache/yum/development:
rm -f /var/cache/yum/development/*xml*

Immediately running yum again fixed this issue and it has not occurred
again.  The metadata files had just been downloaded from the same mirror
prior to the 2.1.7-2 update of yum, but the new version did not like the
files downloaded by the older version.  I do think that deserves some
bugzilla now that others have seen it too.
