Installing gnome-print-0.35-2 leaves the file /usr/bin/redhat-update-gnome-font-install on my disk. If this file is temporary, then (a) it shouldn't be in /usr/bin and (b) it should be removed when it is no longer needed. If it isn't temporary, then the package needs to own it. There certainly should be no orphaned files in /usr/bin.
It isn't supposed to be temporary, it's supposed to be in the file list.
Fixed in 0.35-3
