And that is exactly the same condition as RPMTAG_DIRNAMES contains
/usr/share/icons/hicolor/32x32/apps/ for a package that is installed/ 
erased.

if pkg-contains-directory condition is true, set a boolean to run
      gtk-update-icon-cache /usr/share/icons/hicolor
to ensure that script is run once (or not).
