[O] R-generated images not showing

[William Denton]

This problem started for me a little while ago:  images generated from R source 
blocks no longer appear even though I have images display turned on.

For example, this file:

# -----
#+begin_src R :results graphics file :file /tmp/src.png
x <- seq(-4, 4, length=200)
y <- dnorm(x, mean=0, sd=1)
plot(x,y, type = "l", lwd = 2, xlim = c(-3.5,3.5))
#+end_src

#+RESULTS:
[[file:/tmp/src.png]]
# -----

I don't see the image, I just see the text "file:/tmp/src.png".  When 
image-display is off (C-c C-x C-v) it becomes a link, and when I toggle it back 
on it's just plain text.

The file on disk really is there and is a valid image.

If I run the three R lines in an ESS window (M-x R) then the image pops up in 
its own window, as normal.

I ran "emacs -Q" and loaded up Org and enough Babel stuff to the source block to 
work, and the image appeared inline as it should!  So it's something to do with 
my config [1] but I can't figure out what.

Has anyone ever had this happen, or noticed it recently?  I'm compiling Emacs 
and Org from source and both are current.  I'm not sure what the easiest way to 
identify the problem is.
