This is "taint", something in the secure Blizzard API being corrupted by an AddOn, not a specific bug in LiteBag.

Maybe LiteBag caused it, maybe not, I you find a way to reliably reproduce it please leave a comment in issue #34 otherwise there's no fix and the error doesn't even indicate whether LiteBag is actually the AddOn at fault.
