23.0.95; doc-view-mode with PDF without PNG support |

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.
