I really don't know. I do know that there is another addon that gave me the same error and I had to revert that one also (I think it was Xloot). When these loadup errors happen it kills most if not all of my FuBar addons from loading as well. Reverted - everything runs fine.
Updated to 18118 using WinAceUpdater and I get this on load.

Going back to my older version does not cause errors on load.
