For the general case of making a Requires(post) optional you need to
make sure that the package that you are making optional invokes its
update program when it installs.  For instance:

  Use this when a package drops an XML file in
  %{_datadir}/mime/packages. 

    %post
    update-mime-database %{_datadir}/mime &> /dev/null || :

  $ rpm -q --scripts shared-mime-info
  postinstall scriptlet (using /bin/sh):
  /usr/bin/update-mime-database /usr/share/mime &> /dev/null

For the specific case of gconf schemas, you don't gain much by making
this optional.  The program itself depends on GConf2 so you have to pull
it in for the program whether or not the scriptlet depends on it.  This
in contrast to gtk-update-icon-cache for kde apps and
update-mime-database where the program can run fine without installing
gtk2 or shared-mime-info.
