I am using LO 4.2.2.1 and at last update I had problems with icons got duplicated when more than one document were open. I found out that under ~/.local/share/applications I had old .desktop-links - and unity uses those in your home folder prior to those in /usr/share/applications Now I don't have problems with icons any more.
