I am having the same problem and have an open question. I have worked around it by manually entering IP address, netmask, gateway and dns server in the wireless connection settings (Settings>Network). You might also have to select the BSSID and MAC address. Manual configuration will get you up and running, but it is no fix.

In my case the problem is being caused by apparmor. I have confirmed this by disabling the dhclient profile in /etc/apparmor.d/sbin.dhclient as follows:
cd /etc/apparmor.d
If there is no disable directory create it as follows:
sudo mkdir /etc/apparmor.d/disable
Create a link to the sbin.dhclient profile in the new disable directory:
sudo ln -s /etc/apparmor.d/sbin.dhclient /etc/apparmor.d/disable
The profile is currently loaded and so needs to be disabled:
sudo apparmor_parser -R /etc/apparmor.d/sbin.dhclient
Obviously this is not a permanent solution, and I know nothing about apparmor, so I will raise a more specific question about apparmor and how to modify the profile so that dhclient works correctly when called by NetworkManager.
