Removing the system-ca-cert=true line also worked in my configuration. I didn't notice this being an issue post upgrade because the configuration in the NetworkManager was working. I had to update my configuration in the NetworkManager because of a password rotation and this caused the system-ca-cert=true to be added to the file even though I answered Ignore to the dialog prompt. Upon finding this bug through google I removed the line from the /etc/NetworkManager/system- connections/<essid> file and my wireless connection started to work again.
