Title:
  cancelling shutdown leaves the system in an unusable state

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Steps to reproduce:

  - open gedit, type some text in it, and don't save (this is just a reliable way to reproduce, but ANY open program with unsaved data will do, or even a program not responding
  - From the top-right menu, chose "Shutdown". At the first dialog ("Are you sure you want to...") select Shutdown
  - A dialog will appear informing you that there are some programs that are not closing, and asking you whether to force close or cancel
  - hit Cancel

  Expected: the system should keep working as if you never tried to
  shutdown

  Observed: the system is left in an unusable state where maximized
  windows have no title bar and hence cannot be unmaximized; the dock or
  launcher on the left doesn't show up any more, and there is no panel
  on the top of the screen.

  It looks like Unity (or something) is killed before the dialog
  appears, and is not restarted when you cancel.

  If a dialog gives you the possibility to cancel shutdown, shutdown
  must be cancelled entirely, and in a consistent way. Shutting down
  services that are necessary for the system to be usable should not be
  initiated until it is sure that the system will be shut down
  completely.
