Sorry folks, I didn't realize this problem was so bad. I haven't seen a
bug filed about this on https://foolscap.lothar.com/trac/ or
https://github.com/warner/foolscap/issues , but I just saw email from
the Ubuntu bugtracker because I'm subscribed to Tahoe-LAFS changes, and
the FTBFS bug is threatening to remove Tahoe too (because of the
dependency). When I checked my nightly buildbot job, it looks like the
problem has been happening since exactly the Twisted-17.9.0 release, but
I hadn't noticed (I don't have any sorts of notifications on that
buildbot). It hasn't been affecting our Tahoe unit tests.

Let me see if I can find a fix this weekend, and make a new release. It
looks like Failures are no longer pickleable, which we do in a logging
routine that's exercised by those tests. I've been meaning to replace
that logging with a JSON-based serialization scheme.. I guess it's time
to accelerate that project.
