content_copy: error on import with location options: An illegal choice has been detected...

I have tried on multiple 5.x sites and have never been able to successfully copy a content type from one site to another. Both sites have the exact same modules installed and enabled. I get the following errors every time:

    * An illegal choice has been detected. Please contact the site administrator.
    * An illegal choice has been detected. Please contact the site administrator.

An error has occured adding the content type news.
Please check the errors displayed for more details.

For the record, please also note the typo in the third line of the error message. ;-)

Here's the code I attempted to import:

$content[type]  = array (
  'name' => 'News Article',
  'type' => 'news',
  'description' => '',
  'title_label' => 'Title',
  'body_label' => 'Body',
  'min_word_count' => '0',
  'help' => '',
  'node_options' => 
  array (
    'status' => true,
    'promote' => false,
    'sticky' => false,
    'revision' => false,
  ),
  'comment' => '0',
  'event_nodeapi' => 'never',
  'forward_display_' => '1',
  'image_attach' => '0',
  'upload' => '1',
  'old_type' => 'news',
  'orig_type' => '',
  'module' => 'node',
  'custom' => '1',
  'modified' => '1',
  'locked' => '0',
  'location_maxnum' => '0',
  'location_defaultnum' => '0',
  'location_weight' => '9',
  'location_collapsible' => 1,
  'location_collapsed' => 1,
  'location_addanother' => 0,
  'location_name' => '',
  'location_street' => '',
  'location_city' => '0',
  'location_province' => '0',
  'location_postal_code' => '0',
  'location_country' => '1',
);

Now, interestingly, if I remove all of the location_... options, the type is created successfully. So the problem here would seem to be a compatibility issue.
