You need to specify a language, e.g.

#+begin_src foo
#+end_src

You can use any string for language.  However, if you export to latex
you want to either

a) use a language the LaTeX `listings' package knows about or

b) map your language string to a language existing in the `listings'
package.


I like to put configuration files in src blocks as language `conf', so I
added the following to my .emacs file:

(add-to-list 'org-latex-listings-langs
               '(conf " "))

That is, I set the `listings' packages language to a blank (empty string
doesn't work) and only generic settings (i.e. no specific language
settings) are used when I tex the file.
