Paraphrasing a quote related to Heisenberg compensators: "Fine, thanks."

Obviously, such a loop should never be intentionally - I guess the right way 
to move forwards would be to fix kpa to prevent this kind of loop in the UI 
and to break it automatically upon loading an index.xml file.

I didn't think about indirect circular memberships, but I can't think of an 
obvious reason why they should be any different. (I think there was some 
discussion on the mailing list about circles in member groups *way* ago, but 
I'm too lazy to dig this up…)

Cheers,
