Import Importer

Importing a feed exporter doesn't seem to work.

I create a feed importer, and get it working on a local environment; then I export the importer. The export has elements for name, description, fetcher, processor and parser

I copy the code, on then go to
./admin/structure/feeds/import
on another site instance, and paste in the export code.
An importer is created, but none of the attributes are set, not name, description, nothing.

Here is what I have for export:

$feeds_importer = new stdClass();
$feeds_importer->disabled = FALSE; /* Edit this to true to make a default feeds_importer disabled initially */
$feeds_importer->api_version = 1;
$feeds_importer->id = 'blog_importer';
$feeds_importer->config = array(
  'name' => 'Blog Importer',
  'description' => 'Blog Importer',
  'fetcher' => array(
    'plugin_key' => 'FeedsFileFetcher',
    'config' => array(

      ),
    ),
  ),

          'target' => 'nid',
          'unique' => 1,
        ),
        1 => array(
          'source' => 'xpathparser:1',
          'target' => 'title',
          'unique' => FALSE,
        ),
        2 => array(

        4 => array(

  'import_period' => '-1',
  'expire_period' => 3600,
  'import_on_create' => 1,
  'process_in_background' => 0,
);

Am I missing something here?

thanks
