as maintainer of network-manager-gnome, I received this  bug report
today. The problem is, that n-m-g installs icons into
/usr/share/icons/hicolor. Apparently it needs to call
"gtk-update-icon-cache /usr/share/icons/hicolor". (Is this a new
behaviour of Gnome 2.14?)
Shouldn't other packages that install icons into
/usr/share/icons/hicolor have the same problem? Looking at the Ubuntu
package, the Ubuntu devs wrote a debhelper utility called dh_iconcache,
which creates the necessary postinst/postrm scripts.
But reading  dh_iconcache does not seem to be the way to go.
So, what's the best way to deal with this bug for now? Should I create
the postinst/postrm rules manually?
