Cryptic error message in emacs org-mode following attempted export of file containing image-generating block of R code

I have an R code block that generates an image (see below). Executing the code is no problem (i.e., C-c C-c from within the block generates an image temp.png as expected). However, on export to PDF via LaTeX, there is an error message:

org-babel-sha1-hash: Wrong number of arguments: called-interactively-p, 1

The only other reference to this error (sans the bit about sha1) is from here, Link in a very diffirent context.

The code block closely follows the example from this previous question Embedding R plots in Latex via org-mode Here's the code:

#+NAME: optimal_applications 
#+BEGIN_SRC R  :results graphics :file temp.png :exports both  
require(ggplot2) 
c <- c(.01, .05, .10) 
df <- data.frame(q =
  rep((0:100)/100, length(c)), 
c = c(sapply(c, function(x) rep(x,  101))) )

df$s.star <- with(df, log(-c/log(1-q))/log(1-q))
df$s.star[df$s.star < 0] <- 0

g <- ggplot(df, aes(x = q, y = s.star, colour=factor(c))) + geom_line(aes(group=factor(c))) +
    xlab("Probability that an application is successful") +
    ylab("Optimal number of applications to send")
print(g) 
#+END_SRC

Update: org-mode & emacs version

Org-mode version 7.8.03 (release_7.8.03.267.g1c8eb)
GNU Emacs 23.2.1 (x86_64-pc-linux-gnu, GTK+ Version 2.24.4) of 2011-04-04 on crested, modified by Debian

I think Its not at all related to R, But IIRC its backward incomparable change in emacs 24. full debugger message would help to see where is the problem. and please update which version of emacs and org-mode you are using – kindahero
Thanks - done. Do you think running emacs 24 might be a solution? – John Horton
I just tried your example and it works for me just fine. Your org is newer than mine (release_7.8.02.58.g013b) but my Emacs is newer than yours (23.3.1 (i686-pc-linux-gnu, GTK+ Version 2.24.5) of 2011-08-14 on rothera, modified by Debian). – G. Jay Kerns

After learning that G.Jay Kerns couldn't reproduce with a newer version of Emacs, I upgraded to Emacs 24.0.91.1 and the problem was resolved. FWIW, https://superuser.com/questions/296013/how-do-i-upgrade-emacs-to-the-current-version-on-ubuntu has short tutorial on how to build Emacs from the repository that proved useful.
