Just a thought:

Did you establish that file:///tmp/DenemouAI4WV/denemoprintB.pdf will
open with a pdf reader?

Yes. This file *did* open in a pdf viewer. I believe this was the same problem I had on the GNU/Linux version of the gub build.

the error message comes from print.c as follows:

 EvDocument *doc = ev_document_factory_get_document (uri, err);
  //gint x = 0, y = 0, hupper, hlower, vupper, vlower;//store current
position for reloading
  //get_window_position(&x, &y, &hupper, &hlower, &vupper, &vlower);
  if(*err) {
    g_warning ("Trying to read the pdf file %s gave an error: %s", uri,
(*err)->message);
...

So the call to ev_document_factory_get_document with the uri
file:///tmp/DenemouAI4WV/denemoprintB.pdf is giving that error message.
This is the documentation for that call:

I suspect this is calling ev_document_load ()
which is documented as:

I don't see anything likely there - I have emailed the evince list, in
the hope of some guidance.
