Comment (by raimue):

 I guess that was my fault with https://github.com/macports/macports-
 ports/pull/1463 as I moved gtk from depends_lib to depends_run, so it is
 no longer available at build time. Note that gtk-update-icon-cache is
 provided by gtk2, though, but this port was already using gtk3 before.

 The icons and `.application` files end up in a strange place somewhere in
 the python framework path. Although icons in virt-manager are visible for
 me, I am not sure whether this is correct.

 Usually, gtk-update-icon-cache is run after activating the port, as it
 adds the new files to the cache that is used for all ports.

 {{{
 post-activate {
     system "${prefix}/bin/gtk-update-icon-cache -f -t
 ${prefix}/share/icons/hicolor"
 }
 }}}
