Well, this isn't related to your problem, but you don't need sudo for 
iwlist. Better use sudo only if it is really needed.

How long did you wait before the iwlist command? If it was only a short 
time, it might be a coincidence with the delay of Knetworkmanager. 
Sometimes it takes a short time (1 minute?) until the wireless networks 
are visible here.

What version of Kubuntu are you using? I haven't seen such a behaviour 
with Gutsy or Hardy. And what network card is it? Maybe someone else has 
similar problems, but with my ipw2200 card I haven't seen it.

If the command is really needed, you could make a script in 
$HOME/.kde/Autostart to invoke the iwlist command after login. Something 
like this:

iwlist wlan0 scan
