"You are not in a raid group"

[xandora]

Forgive me if there is already a post regarding this, but the only results I get for searching with this is for 'raid' and 'group'. Quite a lot of posts!

The problem seems to be, that whenever leaving a raid group, or often while I'm in a battleground, I get chat spammed with "You are not in a raid group."

I *think* I remember reading something about Pitbull causing this, but I can't be 100% about that.

Does anyone know what is causing this, and what can be done to fix it?

EDIT: Seems StopAddonMessage might work nicely for me here. Should've checked the recently updated addons list! Anyway, would still like an answer.
