Apparently in my case there seems to be some issue with ConsoleKit that 
I have not yet found out.
KDE's session manager ksmserver ultimately executes some shutdown code 
depending on which window manager is used. I'm currently using the 
"auto" expression, thus what happens during shutdown is that "Stop" or 
"Reboot" is send via DBus to ConsoleKit.

If I do this by hand:

Nothing happens aside from "1329125469.842 type=SYSTEM_RESTART" 
appearing in /var/log/ConsoleKit/history. The same when running the 
command as root or as normal user, with and without the "--system" 
parameter.

I've not yet found out why it's actually not doing anything. Anybody a 
clue here?

As an aside, when running KDM, I found out that loading the "Login" tab 
in "systemsettings" application screws up the KDM configuration in the 
nix store: e.g. it sets the reboot command to /sbin/reboot (which, 
obviously, does not exist).
