With Emacs 23.3.1 in Ubuntu 11.10, and recent org (Org-mode version 7.7 (release_7.7.601.g55e4d), loaded after emacs -Q), consider the following file. When exporting to LaTeX, the rows starting with #+attr_html, #attr_latex, #+caption, do not appear. Both html and odt export are fine.
#+TITLE: Hello, World * An org mode code example #+begin_src org ,#+title: Hello ,* This is an example ,#+attr_html: width="50%" ,#+attr_latex: height=0.5\textheight ,#+attr_odt: (:scale 0.5) ,#+caption: A caption ,[[file:figure.jpg]] #+end_src
