[O] Omitting title in odt-export

[hack writer]

Hi there,

I have problems omitting the OrgTitle from an exported odt-document. Through 
the following preamble in my .org-file I am able to omit most of the default 
title/author/etc. information at the beginning of the .odt-document:

#+ODT_STYLES_FILE: "/path/to/template.ott"
#+TITLE: 
#+DATE:
#+AUTHOR:
#+OPTIONS: ':nil *:t -:t ::t <:t H:3 \n:nil ^:t arch:headline
#+OPTIONS: author:nil c:nil creator:comment d:(not LOGBOOK) date:nil e:t
#+OPTIONS: email:nil f:t inline:t num:t p:nil pri:nil stat:t tags:t
#+OPTIONS: tasks:t tex:t timestamp:t toc:t todo:t |:t
#+CREATOR: 
#+DESCRIPTION:
#+EXCLUDE_TAGS: noexport
#+KEYWORDS:
#+LANGUAGE: de
#+SELECT_TAGS: export
#+BEGIN_ODT
//
// .odt stuff in here
//
#+END_ODT

but there are still two empty paragraphs at the beginning of my file. When 
looking at the source code of the odt-file (content.xml) the empty paragraphs 
are

<text:p text:style-name="OrgTitle">
<text:title></text:title></text:p>
<text:p text:style-name="OrgTitle"/>

before my real text begins.

So how can I get rid of these empty paragraphs (I already tried things like 
title:nil but they didn't work)?
