Sorry, I still can't reproduce the problem.  I created a .emacs file 
just containing the code you posted:

$ cat .emacs
(require 'package)
(add-to-list 'package-archives
              '("melpa" . "http://melpa.milkbox.net/packages/") t)
(add-to-list 'package-archives
              '("marmalade" . "http://marmalade-repo.org/packages/") t)
(package-initialize)
(defvar my-packages
   '(icicles
     clojure-mode
     cider
     magit
     rubocop
     rspec-mode
     el-spec
     feature-mode
     graphene
     color-theme
     password-generator
     dockerfile-mode))
(dolist (p my-packages)
   (when (not (package-installed-p p))
     (package-install p)))

I then started emacs and ran 'M-x list-packages' without a problem.

Are you sure there's nothing else in your various initialization files 
that could be interfering with this?  Don't forget about default.el, 
site-start.el, and .Xresources.  ('emacs -Q' excludes all of these.)

Thanks.  Nothing in it jumps out at me as problematic.
