Comment 3 for bug 1268871

Apparently I have this problem with most of all of my icon themes except Elementary.
In other words Elementary is the only icon theme that has this package-install icon.
find /usr/share/icons -name package-install.*

/usr/share/icons/elementary/actions/16/package-install.svg

These are my currently installed icons:
ls /usr/share/icons -w 1 -d */
