Infinite recursion

Can't prove this is a zenburn issue, but chances seem good that it's related:

Yeah, this patch to color-theme.el helps catch the problem:

When I start commenting out bits of zenburn it gets a little further... the alias for Buffer-menu-buffer-face, the apt-utils stuff...

Hmm, that patch seems a little too eager; it might not be valid.

More on this: it's definitely a zenburn interaction. I put color-theme.el and zenburn.el in the appropriate places and then did

emacs -Q -l <thefilebelow>

(setq load-path (append (list "/Users/dave/.emacs.d/el-get/color-theme" "/Users/dave/.emacs.d/el-get/color-theme-zenburn") load-path))
(require 'color-theme)
(require 'zenburn)
(color-theme-zenburn) ;; comment out this line to see it work
(color-theme-select)
(color-theme-zenburn) ;; as long as color-theme-select is called first, we can do this here 
(color-theme-select)  ;; and call color-theme-select again
