When you manage a specific user and then select the "Permissions" form from the pull down it displays a nice table but immediately after that it shows the following stuff:

ACL_TYPE_GLOBAL_A_AAUTH
ACL_TYPE_GLOBAL_A_ATTACH
ACL_TYPE_GLOBAL_A_AUTHGROUPS
ACL_TYPE_GLOBAL_A_AUTHUSERS
ACL_TYPE_GLOBAL_A_BACKUP
ACL_TYPE_GLOBAL_A_BAN
ACL_TYPE_GLOBAL_A_BBCODE
ACL_TYPE_GLOBAL_A_BOARD
ACL_TYPE_GLOBAL_A_BOTS
ACL_TYPE_GLOBAL_A_CLEARLOGS
ACL_TYPE_GLOBAL_A_EMAIL
ACL_TYPE_GLOBAL_A_FAUTH
ACL_TYPE_GLOBAL_A_FORUM

After that it is just a train wreck of partial tables, no idea what that stuff is but I am pretty sure it is not right. Tested on a clean RC1 install, couldn't find this issue already logged.
