Recent Emacs doesn't respect my mailcap

[Rasmus <rasmus@gmx.us>]

Hi,

In recent Emacs (v25+) doc-view has completely taken opening PDFs from
within Emacs, disregarding my preferences as stated via ~/.mailcap.

Before, mime types of 'application/pdf' would be opened via evince in both
org and gnus.  Now if I'm lucky it opens in doc-view or, worse, (in gnus)
asks me where to save it.

From emacs -q, doc-view respects neither of these settings:

(require 'mailcap)
;; neither of these works
(mailcap-add  "application/pdf" "evince %s")
(mailcap-parse-mailcaps)
;;  ~/.mailcap has the line:
;; application/pdf; 		evince %s;
;; application/*; 	        xdg-open %s;


I looked through etc/NEWS but didn't see any obvious source of this new
behavior.  

Can anybody tell me what might've cause doc-view's recent power-trip? 

Thanks,
Rasmus
