Newest Version breaks admin login

After the last update to 2.1.3 there is a critical error when logging in a user. If it helps there is also a stacktrace I can provide:

PHP Fatal error:  Uncaught TypeError: array_key_exists(): Argument #2 ($array) must be of type array, null given in /bitnami/wordpress/wp-content/plugins/honeypot/includes/wpa_functions.php:52
