Would a timestamp check help ?  You can have several triggers of
course but the triggers system is not designed to have very many of
them.  If you expect to have a dozen icons subdirs eventually then a
trigger for each one would be overkill.

Also, if you have only one trigger you can know that dpkg won't call
your postinst for triggers more than once unnecessaarily.
