You're right but I see an error nevertheless.  Here is my recipe:

       - emacs -Q -nw
       - C-x C-f "a_doc_for_example_a.pdf"
       - M-x doc-view-mode ;; No automatic mode detection (I think it
                           ;; would be the object of another bug report)
       - Answer "y" to the question "Unable to render file.  View
         extracted text instead? "

Here I see an error in 29.4 but the text version is rendered anyway.  In
30 (or master), I see an error and the text version is not rendered.
