I was adding a printer to my system (first time it's had a local printer, first time I've added a printer under Etch; I'd previously, under Sarge, successfully added a remote SMB printer on a windows machine). System was successfully upgraded Sarge->stable Etch recently following release notes' instructions.
I opened Gnome Desktop->Admin->Printing. My printer (Samsung ML-2510, USB) was detected, there was no driver listed; I attempted to add the appropriate downloaded .ppd file from linux printing site but nothing seemed to change in the list. I tried repeating this a few times but apart from it complaining the ppd now already existed in /usr/share/cups/model, it didn't seem to be successfully putting anything in /etc/cups/ppd or updating /etc/cups/printers.conf as might be expected. Then I looked in /var/log/cups/error_log and there were a bunch of cupsdAuthorize: Local authentication certificate not found! messages. Then I discovered I could just point a browser at http://localhost:631 and set it all up that way. No problems getting things working that way (apart from finding I needed to install some foomatic packages, including the one which includes all the ppds) and I'm now printing from all apps just fine.
