The best way to remove duplicate package is using rpm itself and the
--justdb switch. This will only remote entries inside the RPM database
and not on the filesytem itself. If you remove the newest version of
the duplicate packages you can run the yum update again and it will
reinstall the newer versions and all should be good.

Hoping the problem magically goes away by ignoring it is the
"microsoft approach to programming" and should never be allowed.
