I don't know if this has already been raised but I notice on the
package-announce(a)lists.fedoraproject.org list that several Fedora 13
packages keep getting announced, for example, by checking the archives I
see that fedora-release-13-0.6 has been announced 6 times in March and a
further 7 times in February. I suspect there is a glitch in the package
management system somewhere.
