OpenOfficeOrg 3.2 is what is in the ubuntu repos.And that version is buggy particularly with rtf documents. The fix is in 3.2.1.

sudo apt-get remove openoffice*.*
mkdir ~/sc
nano ~/sc/install_OOo.sc

paste in the following. Beware of word wrapping on the wget line

cd ~/Downloads
wget http://ftp.ussg.iu.edu/openoffice/stable/3.2.1/OOo_3.2.1_Linux_x86-64_install-deb_en-US.tar.gz
tar -xvzf OOo_3.2.1_Linux_x86-64_install-deb_en-US.tar.gz
cd OOO320_m18_native_packed-1_en-US.9502/DEBS
sudo dpkg -i *.deb
cd desktop-integration
sudo dpkg -i *.deb

end paste

chmod +x ~/sc/install_OOo.sc
cd ~/sc
sudo ~/sc/install_OOo.sc
