When I export the following simple ditaa block

#+begin_src ditaa :file work-flow.png
    +-------+             +--------+
    |       |             |        |
    | Org   |------------>| Tex    |
    |       |             |        |
    +-------+             +--------+
#+end_src

I get the following in the resulting .tex file.

\includegraphics[width=.9\linewidth]{work-flow.png}

Are you using the most recent version of Org-mode?  Perhaps try starting
up Emacs with a minimal configuration using the -Q flag to the emacs
executable, and see if the problem persists.  If not it is caused by
something else in your configuration.

Is the previous text inserted into your org-mode buffer?  If so then
that is certainly wrong, the only thing inserted into the org buffer as
results should be a file link to the resulting image.

This could be due to the `org-src-fontify-natively', try setting this
variable to nil and see if the problem persists.

On a side note (and personal preference) I would highly recommend using
TikZ for LaTeX documents as the finished product seamlessly integrates
with the rest of the document and scales nicely from posted to post-card
printings.
