Enrico Franconi mentions in passing

"""
the excellent Jorge Pérez  
(from the database community) found a *serious* bug
... in the entailment semantics of BGPs, which nobody  
spotted so far and which invalidates the core of the current  
document.
"""

I don't want to get involved in that thread but I would 
like a pointer to this bug.  Thanks.

Fred
