Ok cool - with one small fix to the plugin, this simple action:

# Update the GTK+ icon cache when an icon is installed.
# See: http://www.gtk.org/api/2.6/gtk/gtk-update-icon-cache.html
/usr/share/icons/hicolor/*:any:gtk-update-icon-cache --quiet --force
/usr/share/icons/hicolor

seems to work.  Now we can apply hundreds (thousand?) of patches of
the following form, and probably in many cases entirely eliminate the
single %post and %postun we've been copying and pasting around.  It
will be awesome.
