After upgrading from V 7xxx to RC2 I occationally get errors emailed to admin referencing files in a "bugs" folder like below. V7xxx had a bugs folder but v8xxx does not.
2010-02-05 09:29:43,578 [9] ERROR BugNET.Global [(null)] - Application Error
System.Web.HttpException: The file '/Bugs/RSS.aspx' does not exist.
