So, there seem to be two things going on here: 1. For some reason, your checkout thinks that the package key is unambiguous, whereas all the checkouts I've run it on think it is ambiguous, and thus must be qualified. I actually can't reproduce your version of the error, but it seems harmless. I think the right thing to do here is force GHC to always print fully qualified; I suspect one of the DynFlags will do it for us. 2. But the test seems to be gaining a new entry entirely, what gives? Well, the test-case is using grep to pull out the part of --show-iface that it cares about. However, --show-iface is using the pretty-printing combinators, so when a field is sufficiently long it spills over to the next line, and it isn't picked up by grep. So the test here is actually a bit broken. I think if we force GHC to have infinite columns that will fix the second problem.

On branch wip/new-flatten-skolems-Oct14, I'm getting this test failure repeatably on test safePkgO1. I'm pretty sure I have done nothing to mess with package hashes!
Any ideas?
