Ubuntu 13.04 i386. Bug is still there.

When I spoof mac via Edit Connections -> (choose connection) -> Cloned MAC address, and after that trying to connect to AP, my connection does not establish. When I trying to connect to WPA2-encrypted AP and open, both have the same issue.

When I spoof MAC with:

sudo ifconfig wlan0 down
sudo macchanger -r wlan0
sudo ifconfig wlan0 up

I have the same issue.
In my /var/log/syslog I have something like:

When I spoof MAC with macchanger utility (or ifconfig hw ether), after some attempts of connection establishing, system resets the wlan0 substituted MAC with the original hardware MAC and after that connects without problems, but with original MAC address:

It seems that this bug exists for a long time and so, must be fixed.

If there's lack of information, I can try to explain more detail with request.
