After resolving conflicts and attempting to build it with some other big branches (such as loop-prevention) we were seeing new kind of test failures in the silo, so I had to pull that branch off for the moment. Here is the log: https://launchpadlibrarian.net/195924595/buildlog_ubuntu-vivid-ppc64el.unity-scopes-api_0.6.12%2B15.04.20150127.1-0ubuntu1_FAILEDTOBUILD.txt.gz In case the full log disappears, here
