Unexpected behaviour using multiple TTY emacsclient

[deech]

Today, I downloaded and installed emacs from CVS. The following
article (http://shreevatsa.wordpress.com/2008/05/11/multi-tty-emacs-on-
ubuntu/) demonstrated using emacsclient to pop up new instances of the
editor, but the behaviour seems unstable.

Here are my test sessions:
------
Open Emacs in new X window.
Start server with 'M-x start-server'
Open a new frame using: emacsclient -c <filename>
Close the client using C-x C-c
  => Unexpectedly, both the server and client disappear.
------
Open Emacs in new X window.
Start server with 'M-x start-server'
Open a terminal session using: emacsclient -t <filename>
Close the client using C-x C-c
  => This works, the client disappears and the server stays up.
------
Open Emacs as a terminal session.
Start server with 'M-x start-server'
Open a new frame using: emacsclient -c <filename>
Close the client using C-x C-c
  => Unexpectedly, the server segfaults and client disappears.
