Sync from F11:
    Tue Apr 21 2009 Than Ngo <than@redhat.com> - 4.2.2-4
    - get rid of the dependency of system-config-printer
    - drop the BR on PyKDE4, system-config-printer-libs it's just needed for
        runtime
    No need to build this (F12 can inherit the F11 build), but we want to keep
        things in sync so the changes don't get lost.
