KDE su & Control Centre

[Stroller]

In the course of trying to get my wireless network card working the 
last couple of days, I've noticed some behaviour in KDE's control panel 
that I wouldn't have anticipated.

If I want to do something which requires root privelidges, KDE 3.4 pops 
up a helpful box titled "Run as root - KDE su" and asks me for a 
password. The FAQ at <http://www.ubuntulinux.org/wiki/InstallingKDE> 
explains this is the user password, not the root one (presumably it's a 
`sudo` window, then).

kWifiManager uses this dialogue to call its configuration editor, so 
that root privileges can be used to set the WEP key & so forth, and it 
works perfectly, but if in Control Centre it seems flakey.

When Kontrol Centre is started, a blue splashscreen is displayed on the 
right-hand side, showing KDE version, hostname, kernel version &c. If I 
enter any of the sections which require superuser access - Network 
Setting or Wireless Network, for example - all the settings are greyed 
out, except for an "administrator mode" button which when pushed 
produces the same "Run as root - KDE su" I described before. In this 
case, though, entering my password just takes me back to the blue 
Control Centre splashscreen.

Is anyone else experiencing this bug, or am I doing something wrong?
