the problem is that people refuse to understand security implications until it is too late and in context of a firewall this is fatal proven by 80 out of 100 alerts on securityfocus for *any* sort of software and before someone comes out with "but konqueror is from a package" well, and you be 100% sure that you not treat /usr/local/bin/ or ~/bin/konqueror the same trusted way and how do you make it sure?
