          :vagrant => {
            :version => '1.8.5',
            :default_ruby => 'ruby-1.9.3',
            :rubies => ['1.9.2'],

            :global_gems => [
              { :name => 'bundler',
                :version => '1.0.18'

            ]
          }
        }
      }
    }
  end
end

I think this is due to a documentation/usage error in the README around user based installs. Try this out:

    chef.json = { 
      :rvm => {
        :user_installs => [
          { :user => 'vagrant',
            :version => '1.8.5',
            :default_ruby => 'ruby-1.9.3',
            :rubies => ['1.9.2'],
            :rvmrc => {
              :rvm_project_rvmrc             => 1,
              :rvm_gemset_create_on_use_flag => 1,
              :rvm_pretty_print_flag         => 1
            },
            :global_gems => [
              { :name => 'bundler',
                :version => '1.0.18'
              }
            ]
          }
        ]
      }
    }
