Subject: 23.0.95; doc-view-mode with PDF without PNG support
Date: Thu, 16 Jul 2009 11:01:43 +0200

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

To reproduce:

   M-x toggle-debug-on-error RET
   M-x toggle-debug-on-quit RET
   C-x C-f some-pdf-file.pdf

I get the message:

    No PNG support available or some conversion utility for pdf files is
    missing.  Type C-c C-c to switch to fundamental-mode, C-c C-t to
    show the doc as text in a separate buffer or k to kill this buffer.

I don't have the png-DLL installed:
  (image-type-available-p 'png) -> nil
Maybe also some of the conversion programs are not installed.  But I  
just wanted to view/edit the PDF file.

Problems:

- The message is too long to be read in the echo area.

- When pressing some key (e.g. `down'), I get "image-next-line: Invalid
  image specification". So the first message disappears as soon as the
  user does a movement.

This hit me several times.  I didn't realize the message so I killed the
buffer and used `find-file-literally'.

I think the right behavior would be either...

(1) Switch to fundamental-mode automatically if doc-view-mode cannot do
    anything useful and just display a message.

(2) Instead of telling about `C-c C-c', `C-c C-t' and `k', use a
    (y-or-n-p) dialog.

I've checked it into the trunk.  I don't think this is serious enough to
commit to the branch.
