YUM updates failing with "Updateinfo file is not valid XML"

My usual command to check for updates is failing with a “Updateinfo file is not valid XML” error (see below). Is this something I can fix from my end?

root@MEMEME ~]# yum check-update
Loaded plugins: langpacks, refresh-packagekit

python-slip.noarch                                            0.6.1-1.fc20                                               updates

Not an answer per se, but there’s a bug:

Not sure if it’s a bug in yum’s parsing code or a bug in the generation of the updateinfo.xml files on the servers. Where’s the forum / irc group to chat with the repo server meisters?
