Office 2007 import/export in OpenOffice.org

The following worked for me:
apt-get install libgif4
wget http://katana.oooninja.com/f/software/odf-converter-integrator-chocolate...
dpkg -i odf-conv*.deb
vi /usr/lib/openoffice/share/registry/modules/org/openoffice/TypeDetection/Types/MOOXTypeDetection.xcu # and modify this line:
<prop oor:name="URLPattern"><value>*.docx *.DOCX *.docm *.DOCM</value></prop>
