When running puppet-lint -f examples/file_line.pp, it fails with an exception:

puppet-lint version: 2.2.0
ruby version: 2.3.0-p0
platform: x86_64-linux
file path: examples/file_line.pp
file contents:

# This is a simple smoke test
# of the file_line resource type.
file { '/tmp/dansfile':
  ensure => file,
} ->
file_line { 'dans_line':
  line => 'dan is awesome',
  path => '/tmp/dansfile',
}

Looks like this is a result of #672, where the fix method for that check changes the tokens array but doesn't update the links between tokens. I'll get this fixed up shortly and push out a 2.2.1 release.
