Aloha Nicolas,
#+call: lines appear to flummox the new LaTeX exporter.
This exports as I expect:
#+caption[Old wood]: Old wood graph.
#+label: fig:old-wood
#+results: old-wood[:file old-wood.pdf]():results file
[[file:old-wood.pdf]]
But this yields "\url{file://nil}":
#+call: old-wood[:file old-wood.pdf]() :results file
#+caption[Old wood]: Old wood graph.
#+label: fig:old-wood
#+results: old-wood[:file old-wood.pdf]():results file
[[file:old-wood.pdf]]
Similarly with tables, where export with the #+call: line looks like this:
\label{tab:old-wood}
\begin{verbatim}
nil
\end{verbatim}
All the best,
Tom
