[O] Bug: wrong-type-argument arrayp nil

[Jon Templeman]

Hi,

(Apologies for not filing this through org-submit-bug-report --- it complains 
about not being able to find org-remember.)

I'm getting the following error, with a minimal org setup, when I try to 
archive a subtree with "C-c $":

    Debugger entered--Lisp error: (wrong-type-argument arrayp nil)
      replace-regexp-in-string("\\[[0-9]+%\\]\\|\\[[0-9]+/[0-9]+\\]" "" nil)
      org-get-outline-path()
      org-archive-subtree(nil)
      call-interactively(org-archive-subtree nil nil)
    
(For what it's worth, and I haven't been able to reproduce it this morning: 
I've also been getting this on and off when putting the cursor over certain 
TODO items in the agenda buffer.)

As far as I can see, everything is up to date:

    (org-version) => Org-mode version 8.2 (8.2-dist @ 
/home/jon/.emacs.d/lib/org/)
    
    (emacs-version) => GNU Emacs 24.3.1 (x86_64-unknown-linux-gnu, GTK+ Version
