I get an PHP error in my error_log with the CommentManager::getCountNewComments() function, on user activity view /user/activity/uid and recent content view /activity.
This error come up on a Drupal 8.2.0 version that is actualy in use in production with many modules installed (Nginx server) :
2016/10/24 11:47:37 [error] 15222#15222: *281253 FastCGI sent in stderr: "PHP message: TypeError: Argument 1 passed to Drupal\comment\CommentManager::getCountNewComments() must implement interface Drupal\Core\Entity\EntityInterface, null given, called in /var/www/html/drupal/core/modules/comment/src/Controller/CommentController.php on line 330 in /var/www/html/drupal/core/modules/comment/src/CommentManager.php on line 190 #0 /var/www/html/drupal/core/modules/comment/src/Controller/CommentController.php(330): Drupal\comment\CommentManager->getCountNewComments(NULL)

So trying to reproduce this on a fresh new basic installation and get similar error on a Drupal 8.2.1 version (apache server) :
