That bug explained my problem and this solution worked with one caveat:

service network-manager stop
rm /var/lib/NetworkManager/NetworkManager.state
service network-manager start

I had to restart the computer because network manager still acted like it was disabled. A session restart probably would have sufficed.

I don't know if this is KDE specific or not.
