[Orgmode] Bug: HTML Export Hangs in 6.04c

[Adr3nal D0S]

This one seems to be fairly easy to reproduce.  But I had trouble
narrowing it down due to the size of the file I was using.

I had a #+BEGIN_EXAMPLE line with no #+END_EXAMPLE line and did a C-c
C-e h to export the file as HTML, Emacs hangs until I C-g.  I did not
test all export modes, but it also occurs with C-c C-e a.

#+BEGIN_EXAMPLE
    Hang the export.
