Thank you for linking to that bug, Marcel. Just to verify what you are saying, would it be right to say that the bug fix caused a a lot of pageviews to be moved from the respective (nonexistent) pages to "-" pageviews? And, does that means that the current estimate of "-" pageviews is more accurate than it used to be prior to the bug fix?
