This may SOLVE the problem for KDE 4.2 under Jaunty:

I can also confirm this bug while trying to connect to a WPA2-PSK encrypted network (Fritz!Box) with my Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02) (Thinkpad T60)

My syslog showed to following entry when trying to connect:
NetworkManager: <WARN> wait_for_connection_expired(): Connection (2) /org/freedesktop/NetworkManagerSettings/Connection/0 failed to activate (timeout): (0) Connection was not provided by any settings service “

After searching the web for a while I found the solution for KDE 4:
1. Close any open knetworkmanager
2. Remove any open Networkmanager plasma-widget
3. Stop Networkmanager (sudo /etc/init.t/Networkmanager stop)
4. Open your favorite package manager and remove knetworkmanager (mainly to prevent it from starting while rebooting and to save disk space as it is not needed any more)
5. Start Networkamanger again (sudo /etc/init.t/Networkmanager start)
6. Add the Networkmanager plasma-widget again to your desktop

Probably you have to reboot or at least log off and log in again.

If you prefer knetworkmanager, remove the plasma-widget instead to prevent ist from starting anything with KDE. This should also do the trick.

Networkmanager seems to get into trouble when being used with to frontends at the same time and KDE seems to start something from the plasma-widget (if installed) even if it is not placed on your desktop.

Adding something to the plasma-widget-network-manager and knetworkmanager packages marking them as conflicting would also solve this for anyone not reading this :-)
