Ubuntu 14.04 lock screen asking password twice

So, everyone loves the new Ubuntu 14.04 lock screen, which looks exactly as the login screen.

But there is an issue with it. If you lock your screen manually (Ctrl + Alt + L) and leave your computer a couple of minutes (untill it locks the screen automatically), when you unlock it, it will ask for your password twice.

Workaround: Go to Settings -> Brightness and Lock -> Lock [OFF] (switch it to off).
