Emacs custom-face丢失/失败，无法识别它写入我的.emacs本身的字体名称

Question

I used the Options/Set Default Font menu item to set my default emacs font to be LMMonoLtCond10 (it brought up a nice font-selector GUI widget to let me do this). My emacs immediately adopted the new font, and I was very happy. I then did Options/Save Options, and on inspecting my .emacs.d/init.el file saw that it had written the following there:

(custom-set-faces
;; custom-set-faces was added by Custom.
;; If you edit it by hand, you could mess it up, so be careful.
;; Your init file should contain only one such instance.
;; If there is more than one, they won't work right.
'(default ((t (:inherit nil :stipple nil :background "white" :foreground "black"     
  :inverse-video nil :box nil :strike-through nil :overline nil :underline nil :slant normal   
  :weight light :height 120 :width normal :foundry "unknown" :family "LMMonoLtCond10"))))

(There are a couple of other faces I've defined below that.)

Unfortunately, if I quit emacs, and restart, it completely fails to recreate the font configuration that I had selected. Instead, I think it's giving me LMRoman-12. Am I doing something wrong, or is this an emacs bug.

I'm using Emacs 23.1.1:

(emacs-version)
"GNU Emacs 23.1.1 (i486-pc-linux-gnu, GTK+ Version 2.20.1)
of 2011-03-05 on palmer, modified by Debian"

on an Ubuntu system.

Sounds like it might be a bug. Mx report-emacs-bug
