Hi. I am still having the problem of bug 17059 cannot view extracted
text from pdf in at least 24.4-rc1. I wonder if someone could take a
look at this?
Thanks in advance for any ideas.

Initially, i was able to reproduce this, using -nw -Q with 24.4.1, on
Debian Wheezy x86_64 - in a console, and in an X terminal
(specifically, urxvt) as well.
i then instrumented the `doc-view-mode` function, stepping through it
line-by-line, and was still able to consistently reproduce the issue.
i then instrumented `doc-view-initiate-display` instead, and stepped
through it line-by-line .... and when it reached `(doc-view-open-text)`
and called it, the text was extracted and displayed in a buffer.
i'm now no longer able to reproduce the issue with -nw -Q.
What might cause this?

The step-by-step gave the process time to finish before it gets killed.

The process is not needed any more because we reuse the output from
earlier Emacs sessions (stashed in /tmp somewhere).

Ah, okay. Thanks for explaining!
So: calling `sit-for` in `doc-view-start-process` solves the problem for
me:
(defun doc-view-start-process (name program args callback)
;; Make sure the process is started in an existing directory, (rather than
;; some file-name-handler-managed dir, for example).
(let* ((default-directory (or (unhandled-file-name-directory
default-directory)
(expand-file-name "~/")))
(proc (apply 'start-process name doc-view-conversion-buffer
program args)))
(push proc doc-view--current-converter-processes)
(setq mode-line-process (list (format ":%s" proc)))
(set-process-sentinel proc 'doc-view-sentinel)
(sit-for 1)
(process-put proc 'buffer (current-buffer))
(process-put proc 'callback callback)))
Is this a reasonable solution?
Alexis.

No, that just changes the odds of the race-condition, but is only an
ugly workaround. IIUC Tassilo installed an actual fix into trunk a few
days ago.
