Maybe in `org-babel-comint-eval-invisibly-and-wait-for-file', but I am not 
sure what/how.
I tried to instrument the function (C-u C-M-x on the function source) and 
run it. And it ran without error when I stepped thru it. Then I removed 
instrumentation with C-M-x and reran - again no error.
I tried removing the *.elc and restarting emacs, but that seems to make no 
difference - the error is still there till I instrument the code.
Until this is sorted out, you might try the instrument/uninstrument gambit 
as a workaround.
