NoMethodError: undefined method `[]' while creating machine from image

[marc-]

After latest (v0.20) chef-privisioning changes following code stops working:

require 'chef/provisioning/docker_driver'
machine_image 'web_server' do
  recipe 'apache'
  machine_options :docker_options => {
      :base_image => {
          :name => 'ubuntu',
          :repository => 'ubuntu',
          :tag => '14.04'
      }
  }
end
machine 'web00' do
  from_image 'web_server'
  machine_options :docker_options => {
      :command => '/usr/sbin/httpd'
  }
end

chef-provisining changed the way how machine_images_spec is stored. Following commit supposed to fix compatibility issue, but it doesn't actually saves machine_options into data:
Before v0.20 (cat data_bags/images/web_server.json)

{
  "id": "web_server",
  "machine_options": {
    "docker_options": {
      "base_image": {
        "name": "chef_web_server",
        "repository": "chef",
        "tag": "web_server"
      },
      "from_image": true
    }
  }
}

After (cat data_bags/machine_image/web_server.json)

{
  "id": "web_server",
  "driver_url": "docker:unix:///var/run/docker.sock",
  "run_list": [
    "recipe[apache]",
  ]
}

From logs:

[2015-03-30T07:53:29+00:00] WARN: Machine options are no longer stored in machine_image_spec.  Drivers that store machine_options will stop working with Provisioning 1.0.
