Kubuntu Bionic: graphical slowdown after installing recent updates

[Rik Mills]

Yes, I uploaded a new version of kinfocenter which does not pull in the
2 packages I mentioned, at least until we get newer versions that work
ok with the rest of our latest builds.

So any fresh install should not get them, and any existing install
should have them be removable or auto-removable with any moans.
