#+CALL get the first row of output table lost when using latex export

[<iemacs@gmail.com>]

Hi,

I encounter a problem when I use #+CALL to create a table with latex
export.  The problem is that the first row of the table is missing, if
the table is created with #+CALL.

My Emacs version is GNU Emacs 24.4.3 (x86_64-apple-darwin13.4.0,
Carbon Version 157 AppKit 1265.21) of 2014-11-04 on Atago.local.  The
Org-mode version is: 8.2.10 from orgmode.org homepage.

I start emacs -q -l emacs.minimal, where emacs.minimal is
#+BEGIN_EXAMPLE
(add-to-list 'load-path (expand-file-name "~/myconfig/org-8.2.10/lisp"))
(add-to-list 'auto-mode-alist '("\\.\\(org\\  |org_archive\\|txt\\)$"
. org-mode))

(add-to-list 'load-path (expand-file-name "~/myconfig/org-8.2.10/contrib/lisp"))

(org-babel-do-load-languages
 'org-babel-load-languages
 '((python . t)
   (latex . t)))
#+END_EXAMPLE

The minimal table example is

#+BEGIN_EXAMPLE
#+NAME: t1
#+BEGIN_SRC python :exports results
  return [['A'],None,[2]]
#+END_SRC

#+CAPTION: T1
#+RESULTS: t1

#+NAME: t2
#+CALL: t1() :exports results

#+CAPTION: T2
#+RESULTS: t2
#+END_EXAMPLE

The latex output of Table T1 is:

#+BEGIN_EXAMPLE
\begin{table}[htb]
\caption{T1}
\centering
\begin{tabular}{r}
A\\
\hline
2\\
\end{tabular}
\end{table}
#+END_EXAMPLE

The latex output of Table T2 is:

#+BEGIN_EXAMPLE
\begin{table}[htb]
\caption{T2}
\centering
\begin{tabular}{r}
2\\
\end{tabular}
\end{table}
#+END_EXAMPLE

Compare with the latex output of the two tables, the first row and the
\hline in the first table is missing in the second one.


Kind regards,
