[O] Problems exporting org-babel to HTML

[Marco Craveiro]

Hi Org-Moders,

I've got a problem with org-babel HTML exports and I wonder if you can
help me. I'm using an up-to-date debian "emacs-snapshot" as follows:

- GNU Emacs 24.0.92.1 (x86_64-pc-linux-gnu, GTK+ Version 3.2.3) of
2011-12-27 on zelenka, modified by Debian
- Org-mode version 7.7

The problem manifests itself when exporting in batch mode (please see
below for source org file):

<shell output>
$ /usr/bin/emacs-snapshot --batch --visit=test.org --funcall
org-export-as-html-batch
Loading 00debian-vars...

Loading /etc/emacs/site-start.d/50psvn.el (source)...
Exporting...
Symbol's function definition is void: copy-seq
</shell output>

This error is very similar to what is described here:

- http://lists.gnu.org/archive/html/emacs-orgmode/2011-07/msg01203.html
- #634695: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=634695

However, from reading that thread it appears I should already have this
fix. Can you please confirm if this is the case? Also, if v7.7 does not
have the fix, is there a workaround? 

The org-file i'm using is as follows:

<org_file>
#+tblname: test_chart
| Day | Expected | Actual |
|-----+----------+--------|
|   0 |        8 |      8 |
|   1 |        7 |      8 |
|   2 |        6 |      8 |
|     |          |        |
#+begin_src gnuplot :var data=test_chart :file test.png :exports both

data using 2 title 'Actual' linestyle 2 with lines
#+end_src
#+results:

</org_file>

Thanks for a wonderful piece of software and for your time.
