Undefined index errors

Seeing these when attempting to log in:

Notice: Undefined index: q in /var/www/html/drupal/sites/all/modules/persistent_login/persistent_login.module on line 266

(really needs to use array_key_exists)

Notice: Undefined index: PERSISTENT_LOGIN__drupal_ in /var/www/html/drupal/sites/all/modules/persistent_login/persistent_login.module on line 275

(same here)

Notice: Undefined index: persistent_login_login in /var/www/html/drupal/sites/all/modules/persistent_login/persistent_login.module on line 382

(and same here)
