I am using a non-temporary cache directory and this makes a difference.

If the document is not yet converted when opening it, it works as you
said.  But if it is, the code which would insert the image after the
conversion never runs and the winprops for the popped up window look
like this:

(#<window 24 on some.pdf>
          (info . #("Page 2 of 4.\n" 0 12 (face bold)))
          (page . 2)
          (overlay . #<overlay in no buffer>))

,with overlay properties (shortened)

(help-echo "Page 2 of 4."
 display "Welcome to DocView! ..."
 window t
 doc-view t)

Then the last sexp in doc-view-new-window-function switches to the first
page, without using the page property.
