My /etc/mailcap defines an appropriate application for pdfs.
The problem is that I replaced the existing entry
for pdf in org-file-apps, so that without the page tag there is no match.

Doing

(setq org-file-apps '((auto-mode . emacs)
            ("\\.mm\\'" . default)
            ("\\.x?html?\\'" . default)
            ("\\.pdf::\\([0-9]+\\)\\'" . "evince \"%s\" -p %1")
            ("\\.pdf\\'" . default)   ;; this was the original
            ))

allows links to pdf's without the page tag to open in an external 
application.
