Description
If an activity module exists in the database, but it's files have been removed, print_recent_activity() (in course/lib.php) will try to include it anyways without checking if it exists. This produces an error message.
The include_once statement is on line 1125 for the current 1.8 stable version (1.484.2.27). It should check if the file exists first like it does in line 975.
Changes made, but there really needs to be a way of flagging this as an error to admin level users.
