I cannot reproduce this, and there is code in startup.el to handle this.

I tried:

cat ~/.emacs

(error "foo")

(custom-set-variables
 ;; custom-set-variables 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.

 '(debug-on-error nil))
(custom-set-faces
 ;; custom-set-faces was added by Custom.

 )


If I use:

emacs --debug-init, I end up in the debugger's backtrace buffer.
