I have installed LibreOffice 4.2.4.1. on ubuntu 13.10 (64 bit)
I have created a Calc Sheet and made it shared document.
But multiple users can not edit same shared document in edit.
i have also used following command but it is not solving my problem.
sed -i 's/X-GIO-NoFuse=true/#X-GIO-NoFuse=true/' /usr/share/applications/libreoffice*
