You seem to have a buggy version of doc-view.el: doc-view-current-files is
not used by doc-view-goto-page in the version that I have, which is the
version bundled with

   GNU Emacs 24.3.50.1 (x86_64-unknown-linux-gnu, GTK+ Version 2.24.10)
   of 2013-04-09

In my version of doc-view-goto-page, there is a comment that says:

,----
|     ;; Update the buffer
|     ;; We used to find the file name from doc-view-current-files but
|     ;; that's not right if the pages are not generated sequentially
|     ;; or if the page isn't in doc-view-current-files yet.
`----

which leads me to believe that you will need to upgrade your version
of doc-view (or perhaps your emacs).
