I'm not sure this is the problem.  The two tests you mention are

  if (terminal_list->next_terminal == NULL)

where terminal_list points to the X terminal about to be deleted, and

  if (terminal_list == 0)

after the deletion of the terminal.  Unless the code has changed since
the last time I looked at it, Emacs uses an initial terminal, which
neither sends nor receives anything, when it is run as a daemon; the
existence of this initial terminal should prevent shut_down_emacs from
being called.

I suspect that closing X also closes the initial terminal, somehow.
