Bug#848523: More info

[Ben Longbons <brlongbons@gmail.com>]

Sorry, I've since upgraded my *entire* system from testing to
unstable, and the problem went away at some point.

If it wasn't a bug in some dependency, my guess is that something had
migrated to testing without all of its true dependencies having
migrated. There are a lot of ways that that can happen - plugins,
changes in the *use* of some already-existing library call (e.g.
accepting new enum values).

You can debootstrap from
http://snapshot.debian.org/archive/debian/20161219T152404Z/ to
investigate the underlying cause, since if it's a missing dependency
problem, it *will* cause problems again sooner or later.

But here's the information you requested, for what it's worth:
