FWIW, I remember seeing discussion of the negative qgroup numbers on- list, but as I don't use quotas I didn't track resolution. So it should indeed be a known issue, but I'm not sure if it's fixed or someone's at least working on it yet or not. But that might give you a duplicating instance if you need one, anyway.
