   Could it be an instance of okular or something was still running,   
   leftover from a previous failed attempt?

   It could be that qpdfview doesn’t accept “-” as a synonym for standard   
   input. It’s a convention understood by some programs (also usable for   
   standard output, depending on context) but not others. You could try   
   more the explicit filename “/dev/stdin”, and see if that works.

   Remember that Okular is primarily a document reader, not a document   
   creator/editor. I’ve never used its Save-As function; occasionally I   
   have used Export to extract selected parts of pages from a document.   
   According to the Okular Handbook   
   , the   
   Save functions are only available if the format-specific backend   
   supports them; plainly the PDF one does not.
