I ran into this issue when a buggy sulogin replacement (don't ask) executed
the command:
/sbin/sulogin /sbin/shutdown -h now 'REMOTE SHUTDOWN REQUESTED'
This corrupted the 'shutdown' executable to the point where it ran, but
gave strange error messages with pieces of the text of the sulogin prompt.
