Fatal errors with drush build command when display suite module is enabled

[davereid]

When running the drush build command with a site with the Display Suite module enabled, you get the following error:

drush: You need to set a name for your layout. Type "drush help ds-build" for help.
Drush command terminated abnormally due to an unrecoverable error.

This is due to the fact that the Display Suite drush integration's ds.drush.inc file has a function named drush_ds_build:

/**
 * Create a basic template and configuration file for a new Display Suite layout.
 */
function drush_ds_build($name = NULL) {
  // Determine the layout name.
  if (!isset($name)) {
    $name = drush_get_option('name');
  }
  if (!$name) {
    drush_die(dt('You need to set a name for your layout. Type "drush help ds-build" for help.'));
  }

The drush --debug output, with an added backtrace in drush_ds_build():
