Subject: Default font in Emacs
Date: Mon, 2 Feb 2009 11:06:35 +0800

Package: Emacs
Version: 23.0.90.1
 
Because I prefer the FreeMono font to the default font provided, I
tweak it in my ~/.emacs like this:
 
  (let ((font (cond ((eq window-system 'w32)
                      "-outline-courier new-normal-r-normal-normal-16-120-96-96-c-*-fontset-auto2"
                     )
                     ((eq window-system 'x)
                      "FreeMono-13"
                     ))))
    (set-default-font font)
    (add-to-list 'default-frame-alist `(font . ,font)))
 
When I start emacs as a daemon:
 
  $ emacs --daemon
 
The cons cell added to `default-frame-alist' seems to be '(font
. nil). This causes a segfault when running `emacsclient -c':
 
  Program received signal SIGSEGV, Segmentation fault.

The bug is in your .emacs

C-h v window-system RET

Documentation:
Name of window system through which the selected frame is displayed.
The value is a symbol--for instance, `x' for X windows.
The value is nil if the selected frame is on a text-only-terminal.

When "emacs --daemon" starts there's no X frame.
