I found it. It is in a PDF of 5.2 MByte, containing 631 pages of the
total proceedings. I have extracted the relevant 11 pages of Havoc's
contribution about GConf (it's only 60 kB of PDF now).

I have uploaded it to

    http://www.linuxprinting.org/kpfeifle/LinuxKongress2002/GConf-at-OLS2002.pdf

Someone should grab it from there and put it onto a more prominent and
easy-to-find-and-remember location.
