Coding Error in get_value_options()

False code:

// For all possible content types, load the appropriate state machine and
    // determine possible states.
    foreach ($node_types as $type => $value) {
      $machine_type = variable_get('state_flow_' . $type, 'state_flow');
      if (!isset($machines[$machine_type])) {

Correct code:

// For all possible content types, load the appropriate state machine and
    // determine possible states.
    foreach ($node_types as $type => $value) {
      $machine_type = variable_get('state_flow_' . $type. 'state_flow');
      if (!isset($machines[$machine_type])) {
