Public bug reported:
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.
