I had this problem in org mode for org store/insert link to file which was 
solved by the following. 

— quote

 '(org-file-apps
   (quote
    ((auto-mode . emacs)
     ("\\.mm\\'" . default)
     ("\\.x?html?\\'" . default)
     ("\\.pdf\\'" . default)
     (t . emacs))))            ; This tells Emacs to open any unrecognized file.

— end quote
