BuddyPress.org

With the new 2.8.1 and BuddyBar, I get this on my bar:

Fatal error: Call to undefined method BP_Roles::_init() in /home/public_html/community/wp-includes/wpmu-functions.php on line 317

I did apply this patch but no help in mudville. In fact, if I make THAT change, I get the error sitewide.
