AFAIK, KDE does not use xscreensaver but provides its own screensaver
(and locking) functionality as a part of the "kdesktop" process (which
is normally started by kdeinit).
You can check if kdesktop is running with "ps -ef | grep [k]desktop".
You should see the process listed as "kdesktop [kdeinit]". (It is very
unlikely that kdesktop is not running when you have a KDE session, but
it does not hurt to check.)

I don't know all the details, but I know that you should be able to lock
the screen under KDE with the following command:
dcop kdesktop KScreensaverIface lock
Maybe that will give you a helpful error message if it does not work;
also check ~/.xession-errors for anything related to the screensaver.

~/.kde/share/config/kdesktoprc
This configuration works for me:
$ awk '/\[ScreenSaver\]/,/^$/' ~/.kde/share/config/kdesktoprc
[ScreenSaver]
DPMS-dependent=false
Enabled=true
Lock=true
LockGrace=60000
Saver=KRandom.desktop
Timeout=300
(You can run the same "awk ..." command to see the relevant part of your
own configuration.)
You can change these settings in the KDE control center ("Appearance &
Themes > Screen Saver").

I have the same packages installed. (I am currently on KDE 3.5.6 from
experimental, but I never had any problems with version 3.5.5-1 either.)
If all else fails you can create a new user and test if that user can
lock the screen normally. That will at least tell you if you have a
system-wide problem or one related to your regular user's configuration.
