Looks like this is an issue with the underlying PackageKit.  Reassigning there.

Comment 2 Richard Hughes 2009-09-01 13:19:34 UTC
It's a backtrace from deep in the internals of yum. Reassigning once more.

Comment 3 seth vidal 2009-09-01 19:16:52 UTC
Can anyone make this happen on yum from rawhide?

Comment 4 James Antill 2009-09-18 16:00:49 UTC
To trigger it you want a repomd.xml file in the repo. cache ... which doesn't parse.
Not sure how the hell this happens, but we probably shouldn't die. Fix posted for approval upstream.
