Wrong permissions in /tmp/verifier/gems/[bin/cache/gems] (?) / broken caching with 1.4.0.beta.2

Up until test-kitchen 1.3.1 I could use vagrant-cachier to cache the whole /tmp/busser/gems directory by adding this to my global ~/.vagrant.d/Vagrantfile:

 ruby
# global Vagrant configuration
Vagrant.configure("2") do |config|

  # enable cachier globally
  if Vagrant.has_plugin?("vagrant-cachier")
    config.cache.scope = :box

    # cache bussers for test-kitchen
    config.cache.enable :generic, {
      "busser" => { cache_dir: "/tmp/busser/gems" }
    }
  end
end

This gave me a noteable speedup for running the kitchenci tests. Without caching, it would download and install the bussers for every kitchenci run again.

I have noticed that the path changed to /tmp/verifier/gems now, but once I try to cache this path with 1.4.0.beta.2 the kitchen run will fail with some write permission error.

I'm still investigating the exact cause for it as it worked without problems with 1.3.1. One thing that looks suspicious to me is the ownership of the files in /tmp/verifier/gems/[bin/cache/gems] directories:

drwxrwxr-x  5 vagrant vagrant 4096 Mar 29 14:12 thor-0.19.0/

Except for the busser gem itself they are all root owned. Is this as expected?

    This is the exact error I get when running kitchen verify with caching of the /tmp/verifier/gems directory enabled:
