Bug Description

As the title says you can bypass lock screen by right clicking on indicators several times and if you had Terminal window opened and focused you can issue commands.

How to reproduce:

1. Open Terminal and play some music with mplayer
2. Lock the screen using one of the shortcuts (Super+L or Ctrl+Alt+L)
3. Right click a couple times on keyboard indicator
4. Now you can use Ctrl+C shortcut to stop your mplayer playing music in Terminal and issue any command you want. You can also open another Terminal window.

I had no problem to start this way synaptic with synaptic-pkexec command and then typing my password. This all went to Unity under lock screen.
