That seems really a problem.
It seemed to me rare when someone talk about receiving wrong PUSHes. This didn't have very sense.
Then, Someone begin to talk in the GDF about if Gnutella was under attack. And then someone find the bug. I cant believe these people are so lame to take other program, modify it, and commit such a error.
