Code block evaluation export bug ? (was: Re: Export an org file from the command line in the background)

[Nick Dokos <nicholas.dokos@hp.com>]

While testing my response to Viktor's question, I ran into a problem.
I used a test file that is slightly modified from a previous post of Tom Dye's:

--8<---------------cut here---------------start------------->8---
* R tables

#+TBLNAME: tbl-1
| column1 | column2 |
|---------+---------|
|      45 |      34 |
|      77 |      56 |

#+tblname: tbl-2
| col1 | col2 |
|------+------|
| a    | b    |
| c    | d    |

#+tblname: tbl-3
| c1 | c2 |
|----+----|
| A  | B  |
| C  | D  |

#+BEGIN_SRC R :var x=tbl-1 :var y=tbl-2 :var z=tbl-3 :colnames yes :exports both :results value
z
#+END_SRC


--8<---------------cut here---------------end--------------->8---

Evaluating the code block correctly produces the result

,----
| 
| #+results:
| | c1 | c2 |
| |----+----|
| | A  | B  |
| | C  | D  |
`----

but exporting (to ascii, PDF, HTML or ODT) chops off the first row of the result. For example, here
is the ascii:

,----
| 
|   c1   c2  
|  ----+----
|   C    D   
`----

HTML produces:

,----
| <pre class="example">
|   c1 c2
| 1  C  D
| </pre>
`----

Latex:

,----
| \begin{center}
| \begin{tabular}{ll}
|  c1  &  c2  \\
| \hline
|  C   &  D   \\
| \end{tabular}
| \end{center}
`----

ODT:

,----
| <table:table table:name="" table:style-name="OrgTable">
| <table:table-column table:style-name="OrgTableColumn"/>
| <table:table-column table:style-name="OrgTableColumn"/>
| 
| <table:table-header-rows>
| <table:table-row><table:table-cell table:style-name="OrgTblCellT"><text:p text:style-name="OrgTableHeadingLeft">c1</text:p></table:table-cell>
| 
| <table:table-cell table:style-name="OrgTblCellT"><text:p text:style-name="OrgTableHeadingLeft">c2</text:p></table:table-cell>
| </table:table-row>
| 
| </table:table-header-rows>
| 
| <table:table-rows>
| <table:table-row><table:table-cell table:style-name="OrgTblCellTB"><text:p text:style-name="OrgTableContentsLeft">C</text:p></table:table-cell>
| 
| <table:table-cell table:style-name="OrgTblCellTB"><text:p text:style-name="OrgTableContentsLeft">D</text:p></table:table-cell>
| </table:table-row>
| 
| </table:table-rows>
| 
| </table:table>
