I use Ubuntu and LibreOffice. I've tried to install the Breton Language Grammar Checker Extension ( http://www.languagetool.org/br/ ) but when I try to enable it in LibreOffice I get a box that pops up full of, what is for me, incomprehensible code. In the box Jave is mentioned a lot and an 'UNO exception occurred' is also written. I've installed the version of Jave that was recommended for Ubuntu but this has changed nothing.
Thanks for your help in advance.
