I see the same.  Not sure why this is happening but you can fix it but
adding any line after the saveas statement that would generate a value,
e.g. just a "1" will do:

#+begin_src org
  ,#+begin_src octave :results file :dir "data/images" :file "figure1.png"
  clf ();
  surf (peaks);
  saveas (1, "figure1.png");
  1
  ,#+end_src
#+end_src
