undefined method `each' for nil:NilClass

I've been seeing this error message when trying to install ganglia::gmetad

Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Failed to parse template ganglia/gmetad.conf.erb:
Filepath: /etc/puppet/modules/ganglia/templates/gmetad.conf.erb
Line: 44
Detail: undefined method `each' for nil:NilClass
on node log.example.com
Warning: Not using cache on failed catalog
Error: Could not retrieve catalog; skipping run

This is the manifest code:

$clusters = [
      {
        name     => 'test',
        address  => ['test1.example.org', 'test2.example.org'],
      },
    ]

  class{ 'ganglia::gmetad':
    clusters => $clusters,
    gridname => 'my grid',
  }

Seems to be a problem with the future parser

This seems to be fixed in PR #27
