Hi Martin and all,

Please note that if you have org-babel activated, then exporting
any #+begin_src XXX block will make use of org-babel, and therefore that
any problems may be org-babel problems (and therefore that a [babel]
subject tag may be appropriate.) I think it's reasonable to treat this
as a [babel] thread for now.

Having said that, I'm not knowledgable enough about the export mechanics
to have come up with any good suggestions here. Could you cut down your
large file until you find a reasonably small version that still shows
the problem, and then post that?

Fwiw:

Org-babel should have inserted

[[file:./test.pdf]]

which should export to

\includegraphics[width=10em]{./test.pdf}

I can get something similar to the \hyperref by using a named link

[[file:./test.pdf][./test.pdf]]

which exports to

\href{file:///tmp/test.pdf}{./test.pdf}

(I don't know what the difference is between href and hyperref nor what
determines which is used.)
