 I've just checked a  patch in which should fix this:

commit f2211e9115e9ffe9cd635fd999b7c2a7a108db5f

...but that's more a defensive fix than anything, as I don't see how
that exception is possible in a single yum run ... could you explain
what PK is doing? What does print self._oldRepoMDData show?
 Are you doing anything weird, like "del repos.repoXML"?

 That's not true, even moving from "group:all" to "instant" will still
take the same code path through _commonLoadRepoXML().
