Menu links: PDOException caused by unresolved parent_identifier

Since upgrading to features 2.2 I'm getting a ton of notices as well as a PDOException whenever features is attempting to import a menu item for which a parent cannot be found in the same feature (it even throws this exception if the parent is available in another feature, or in the drupal menu_links table)

Here's the output I'm getting when enabling the feature during a drush site-install:
