Hi Mario,

Thanks for posting your example Org file.  Now I am able to reproduce
the problem and know where the bug is.

Just as what you said, the problem is caused by the last line that
contains strings "double[9]" and "double[3][3]".  Here "[9]" and "[3]"
are considered footnote references (and I don't think this is what you
expected), so some code is executed to find the footnote definitions.

The problem happens when the *second* "[3]" is being processed.
Strictly speaking, the second "[3]" is NOT considered as a footnote
reference according to ``org-footnote-re'' (see org-footnote.el), but
some code in org-docbook.el and org-html.el does not use
``org-footnote-re'' and still treats it as a footnote reference.  This
inconsistency causes the error you saw, which is only visible in
org-docbook.el.

Before I try to fix this problem, I would like to get the confirmation
from Carsten on the footnote syntax: whether the second "[3]", which
immediately follows a character "]", should be treated as a footnote
reference.

To get around of the problem, you can try changing the last line to
something like:

  - =double[9]= was less efficient that =double[3][3]=,

Please let me know if you have further questions.
