Malformed info.yml will take down your site

Just place this module in your D8 site, clear the cache and it will throw and exception.

I nuked my test site and started a new install and got an error message:

Fatal error: Call to undefined function Drupal\Core\Render\system_page_attachments() in /Users/jmburnz/Sites/contrib/drupal-stable/core/lib/Drupal/Core/Render/BareHtmlPageRenderer.php on line 65

This lead me to the malformed yml file.
