After compiling from a fresh pull from Git today, setting org-file-apps is 
causing problems.  I have this so make Org exports to PDF open in evince instead 
of Emacs's built-in docview:

(delete '("\\.pdf\\'" . default) org-file-apps)
(add-to-list 'org-file-apps '("\\.pdf\\'" . "evince %s"))

This was fine last week, but today, on startup, either line causes this error:

Symbol's value as variable is void: org-file-apps

If I C-x C-e those two lines after startup has halted, there are no complaints.

Did something about this variable change?  I had a bit of a look but didn't see 
what could have caused it.
