Error when using :session :colnames yes :results graphics on an R code block

Error when using :session :colnames yes :results graphics on an R code block

[Kodi Arfer]

If I run Emacs with

     emacs -Q --eval '(progn (add-to-list (quote load-path) 
"/home/hippo/.emacs.d/elpa/org-20161224") (add-to-list (quote load-path) 
"/home/hippo/.emacs.d/elpa/ess-20161223.108/lisp") (require (quote 
ess-site)))'

, open an Org file containing

     #+BEGIN_SRC R :session :file /tmp/foo.png :results graphics 
:colnames yes
     library(ggplot2)
     qplot(c(1, 2, 3), c(2, 4, 9))
     #+END_SRC

     #+RESULTS:
     [[file:/tmp/foo.png]]

, add R to org-babel-load-languages, and hit C-c C-c on the
code block, I get the error:

     cons: Wrong type argument: listp, "x
     1"

If I remove ":colnames yes", the error doesn't happen and the
file is produced as expected.

The full backtrace is:
