Hm, could you please elaborate what you mean by "effect" and "cause"
here?

This error has nothing to do with the X connection problem, right?

server-start gets called from kill-emacs-hook. It first deletes the
server-process, and then calls server-running-p, which unsuccessfully
tries to connect to the server's socket (server.el, revision 1.177):

      (when server-process
        ;; kill it dead!
        (ignore-errors (delete-process server-process)))
      ;; Delete the socket files made by previous server invocations.
      (if (not (eq t (server-running-p server-name)))

However, please note that make-network-process in server-running-p is
inside a condition-case. (Which doesn't prevent it from hitting my
gdb breakpoint in Fsignal.)

With 1.175 it doesn't hit Fsignal. But I'm not sure if there really is
a problem in 1.177.
