Hello All,
I’m using ubuntu 12.04 LTS and it Libreoffice. I can not start libreoffice while double click on it icon. I run in the terminal this command and got this error. Please help me,

Are you using the Ubuntu-supplied version of LO or the one available via the web? Which particular version (number) of LO?
