Occurred this morning while working with some large text files. Update to Trusty was taken last night. The desktop froze, shut down and re-started after a few seconds as though nothing had happened.

Hey folks, trying to necro a bug that was marked fixed and released more than two years ago is unlikely to help you. You would be better off following a newer similar bug in the software release you're using, like #1282884.
