----------------------

Then find a pdf with text.
In emacs23 you immediately get the unable to render file prompt.  In 24,
you get the pdf raw.  Now do escape-x and type docview-mode.
Now you get the unable to render file prompt.  When you hit y to the
view extracted text instead, you get the following:
DocView: process pdf->txt changed status to killed.

By the way, this is done from a text console.
