Hmm what kind of mistake are you talking about? I like polkit, but
I don't think it fits CUPS design, for printd (a possible CUPS replacement)
it will make all sense.

It's not exactly a crash, the way s-c-p-kde is working today requires it to
run printer-applet as root (which is what some distros do), or have CUPS
not to ask password for local admin tasks (Ubuntu case), and in Debian
at the time I started print-manager it simply doesn't work. The reason
being that it couldn't show a CUPS password dialog and all cups
communication was in the GUI thread so it would block.. In other words
it wouldn't have an easy fix.

s-c-p-gnome now uses polkit but I don't know exactly how does that work
and since CUPS has a method to handle password I think this makes
the problem much more complex.

Right, I'm really not sure about the location, since it's a hardware
component I'd say kde workspace under kcontrol dir seems a good
place but whatever helps packagers or anything is fine to me :)
