@r-a-y: Yes, I did.

@TheEasyButton: That’s a bit too complicated. I could just remove the buggy group and I think that would solve the problem. I’m merely leaving it out of curiosity to see if there is a real fixable bug behind it. Down-/Upgrading to alpha 6 would also just be a workaround and I think the group-deleting would be the easier workaround in this case.

I also did not have any trouble with the update otherwise. Everything (except this one group) works smoothly and bbPress does not complain about anything. So I guess the update worked.

But thanks for the input.
