I also think that the mentioned KDE bug is a different bug. It's about NetworkManager-kde4 not been able to save (or show) the used password. My password is saved and I can see it if I check the "Show password" field. Also, nm-tool doesn't show my network at all. (It does show it after I do the trick with iwconfig, and after that kwallet pops up and plasma-widget-network-manager connects to my network normally.)
