There is a bug in SecureGroupHeaders.lua file in PTR build 14911 (was probably present in earlier build as well) in the secure aura header section with the local function "configureAuras" and when we enable consolidated or weapons (enchants) into the header.
First of all, I'm sorry for the external link for details about it, but as a developer myself, I like to have detailed bug report with screenshots inside, etc. Something I'm not really able to do on the WoW forums.
The bug is detailed at this address, post #1:

An "how to fix it" in include in the post #2
Thank you for reading! Hoping to see it fixed in the next PTR builds before 4.3 goes live else we (addons authors) will have some problem with our buffs addons.
