Comment 18 for bug 1359211

Backport to wily is being prepared here:
 - https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/landing-027

That will go through the SRU process, so it will take a while to reach everybody. If you want to test it in the meanwhile, you can just use that PPA (to be removed once installed, as it might then be reused by other projects).
