Excuse me .

which is
include in Org Format Latex Header defautly.

I cannot be sure whether "waterloo" sees the same problem (from his
description, it seems that he gets just an empty square which
indicates
additional/different problems - maybe missing the dvipng program?),
Yes, this seems to be a different problem. Maybe the problem is
thatthe matrix environment must be inside a math environment?
but
I do see a problem. Here is the org file:
,----
| #+LaTeX_HEADER: \usepackage{amsmath}
This is actually not necessary, I was mistaken here.

| * foo

| \[
| \begin{matrix}
| 1&d\\
| d&d\\
| \end{matrix}
| \]

I can export this to LaTeX just fine (and I need the additional
header,
at least in that case - I have not tried without it). But when I try
the
preview C-c C-x C-l on the fragment, I get the preview of the matrix
twice with an empty square separating the two instances. I attach a
PNG
image of the result. I checked the image that is produced in the
ltxpng
subdirectory: it's just the image of the matrix, no problem there.
Hmm, another fun and interesting bug!
Fixed now. Thanks.
