Psych/papertrail (reify) causing: Tuple cannot be created via allocate()

[jc00ke]

I'm testing this on ffd327f

• clone calagator/calagator@479c68a
• bundle
• bundle exec rspec spec/models/venue_spec.rb:327

I am running into this same issue, but I'm not using papertrail. Just Rails 4.2.0 and Guard. Here are my steps to reproduce:

gem install rails -v 4.2.0
rails new testapp
echo "gem 'guard'" >> Gemfile
bundle
guard init
bundle exec guard

@andrewhavens @jc00ke
This is a known issue with psych 2.0.9 for all serialization/deserialization of all Hashes. I recently pushed a fix to psych (ruby/psych#218) that should have solved this problem for most cases - please update your psych version to at least 2.0.10.

The only case that this remains unfixed for is if someone is using a subclass of Hash that they implicitly serialize/deserialize. See this issue (ruby/psych#220) and the longer discussion in this issue (ruby/psych#216).

@jemc Thanks! Ran bundle update psych (which installed 2.0.11) and the error went away.
