The point of the suggestion I posted is to avoid *unnecessary* dependencies 
like this one as well as unnecessary calls to touch and 
gtk-update-icon-cache.  The part of my original message you quoted above 
explains why I think it doesn't matter if touch is available at %postun time 
or not (my assumption is that coreutils can't be removed while gtk2 or 
kdelibs is installed).  If I'm correct and it doesn't 
matter, "Requires(postun): coreutils" is just unnecessary bloat in repodata, 
rpmdb and spec files.
