Error: Protected multilib versions: redhat-lsb-4.1-4.fc17.x86_64 != redhat-lsb-4.0-11.fc17.i686

Uninstalling redhat-lsb-4.0-11.fc17.i686 allows the upgrade to go through.

But clearly the wrong i686 package is in the repos.

Those two versions should clearly match.
The redhat-lsb-4.1-4.fc17.i686 packages should be pushed to x86_64 updates.

Could someone add some presubmit test to enforce such things?
This isn't the first time such multi-arch package level mismatches have happened in the fedora x86_64 repos.
