Comment 7 for bug 1903814

I can confirm that the patch applies and the build seems to pass OK in a -security enabled PPA (https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/4439).

But it produces some test failures/regressions, which we need to work on before we can get this moving: https://bileto.ubuntu.com/excuses/4439/bionic.html
