[Message part 1 (text/plain, inline)]

Hello!

The X client versions of GNU Emacs 23.0.x and 23.1.50 do not fail to  
create a preview when my init file contains

	 '(TeX-PDF-mode t)

and they also do not fail when this line is commented. The Cocoa  
variants of the same versions do all fail when this customisation is  
set and they do not fail when it not set (commented). Ghostscript  
8.61 always succeeds to run, and so do all the utilities used by AUCTeX.

The tests were run from auctex-11.85/preview/circ.tex. Systematically  
the first eqnarray environment (line #67ff) was marked as a region to  
be previewed. Caching the preamble was always off, except for a last  
try (which also failed). TeX Live 2008 was last updated a few weeks  
ago. PdfTeX is an updated version without the font cache bug (which  
particularly became "famous" for Mac OS X 10.5, Leopard, users). A  
similar report went to the AUCTeX developers.

Logs from the TeX runs to create the previews are recorded. This  
failure exists over one year. Carbon Emacsen do not have this  
failure. I am using Mac OS X 10.4.x (Tiger).

There's something the technicians need to learn from the artists. If  
it isn't aesthetically pleasing, it's probably wrong.

Hello!

The most easy way to reproduce the described behaviour is to launch  
Emacs.app with -Q and then execute/evaluate in its *scratch* buffer a  
bit of Elisp code:

	<extend load-path that the AUCTeX files are found>
	  (load "auctex.el" nil t t)
	  (load "preview-latex.el" nil t t)
	 (setq TeX-PDF-mode t)

With the last line Emacs.app always fails to produce previews. The  
setting can also be made active for a particular buffer by executing  
the TeX-PDF-mode function. The interesting thing is that, when TeX- 
PDF-mode is nil in the buffer you can create a preview, when you set  
it to t you can't, when you set it to nil again, yes, you can again!

When in doubt, use brute force.

If this is still an issue with current Emacs, AUCTeX, and non-ancient OS
X, please open a new report. Thanks.
