I will make the changes shortly then, apologies as I thought this was part of the core flow-tools package ( you didn't state otherwise in your original bug).
netmon has modified the warnings patch so that it won't make the changes in the first place. Thanks for the report Alexander. (this should be committed shortly by someone other then me as I can't get to my commit box atm. Thanks ka0tic).
