Title:
  unity retains focus on virtualbox session when locked

Status in Unity:
  Confirmed
Status in “unity” package in Ubuntu:
  Confirmed

Bug description:
  While using virtualbox in fullscreen mode, CTRL + ALT + L, leaves
  focus with the virtual machine. However this still locks the host's
  unity session. This leaves all key events trapped in the virtual
  machine, so typing in your password becomes impossible. After a reboot
  all functionality returned.

  This could be a potential security hazard, depending on the virtual
  machine being used, as it allows arbitrary commands to be executed
  through a locked unity session without any authentication.
