Comment 2 for bug 1215282

Thanks for finding the upstream bug. But it looks like upstream is talking about a regression introduced by switching to safe_yaml. In Ubuntu, the safe_yaml module change happened in 2.7.11-1ubuntu2.3, not 2.7.11-1ubuntu2.4.

It looks like 2.7.11-1ubuntu2.4 included a roll-up of various different patches. To debug, perhaps we can bisect this? https://github.com/puppetlabs/puppet/commits/2.7.x might be a source of the individual patches - but they don't seem to line up exactly.
