/etc/cups/cupsd.conf file overwritten by kdelibs-data or other KDE package?

Please see:

Ubuntu Forums - Permissions on /dev/usb/lp0 and CUPS non-printing
http://ubuntuforums.org/showthread.php?t=47626

for full details. Summary is as follows:

1. My CUPS-driven USB printer in Kubuntu Hoary suddenly stopped working one day.
 I found that I had to change permissions on /dev/usb/lp0 to allow "all" to
read and write before it would print again, even though I was the only user.

2. Because the /dev tree is re-populated after each reboot, it was inconvenient
to do this after each re-boot.

3. I then examined my /etc/cups/cupsd.conf file and found that it was different
from what I had from cupsys.

4. After

sudo apt-get remove --purge cupsys cupsys-client cupsys-bsd
sudo apt-get install cupsys cupsys-client cupsys-bsd

I found that the new cupsd.conf file was different from the saved cupsd.conf.O
file. The latter was from KDE; the former from Easy Software.

5. After re-installing with the original cupsd.conf file, printing was restored
with no need to change /dev/usb/lp0 permissions.

6. I have not manually changed my cupsd.conf file except for enabling printing
from other printers on my LAN. Therefore, my /etc/cups/cupsd.conf file must
have been overwritten by some KDE package that I have recently installed. All
my packages are from Ubuntu mirrors and from the KDE 3.4.1 and KOffice 1.4 deb
sites given on the Kubuntu website.

7. Given the number of printing problems reported on the Ubuntu Forums, if the
/ect/cups/cupsd.conf file is indeed overwritten by a KDE package, and is causing
some trouble, I think you should know.

8. There seems to be no scope for appending attachments at the Bugzilla site. I
can make my cupsd.conf and cupsd.conf.O files if you need them.
