lisp error: "unbalanced begin/end_src blocks with #(\"#+BEGIN_SRC C"

Running org-export-as-latex on:
> #+STARTUP: beamer
> #+LaTeX_CLASS: beamer

> double tmp0 = yp[0];

generates the following traceback.  Adding a "* foo" line above the BEGIN_SRC avoids the problem.

Yup - Robert Goldman ran into this too a couple of weeks ago - see the thread at
