[Bug-AUCTeX] preview-latex works with latex, but not with pdflatex

[Søren Raunsbæk Jørgensen]

Hi

I run auctex 11.84-0ubuntu1.

I have some trouble with preview-latex when I use pdflatex. The attached 
file dummy.tex is a minimal latex document illustrating my problem.

You can preview dummy.tex as well as compile it for both latex and 
pdflatex. (C-c C-c ; C-c C-p C-d) However in dummy.tex the option to the 
package color is deliberately set wrong to dvips. Preview-latex will not 
preview anything, when setting the color option right to pdftex. (C-c 
C-p C-c C-d ; C-c C-p C-d) If you instead change the preview option to 
dvips and run latex (not pdflatex) everything will preview and compile 
correct.

Note that if I change the command note to only use parbox and not 
fcolorbox in dummy.tex the behaviour is still the same. If I just add 
"\usepackage[pdftex]{hyperref}" or "\usepackage[pdftex]{xcolor}" to 
dummy.tex, nothing will be previewed even though I do not use anything 
from the package.
