The question says it all. I had a working icon set on LibreOffice 4.1 that got messed up due to an upgrade to 14.04.
How can I install my Faenza icons again?
[Note: because icons are for the Desktop users (and not server users), the following steps use as little terminal as possible. For noobs: nautilus is the standard file manager.]
Download the icon pack from http://dfiles.eu/files/k2dq3mwkq
Go to the directory in which you downloaded it, right-click on the zip file and choose "extract here"
Navigate in the just extracted folder to "LibreOffice Pack Icons-0.3.8-a-1/LibreOffice 4.1.0 (Sidebar)/Faenza icons LibreOffice 4.1.0"
Open a terminal and type sudo nautilus /usr/share/libreoffice/share/config/
In the Nautilus window that opens rename images_crystal.zip to something like images_crystal.zip_old and keep the Nautilus windows open.
Copy the images_crystal.zip file from the Faenza icons LibreOffice 4.1.0 folder you have kept open and paste it in the windows displaying /usr/share/libreoffice/share/config/.
Close nautilus and open LibreOffice.
In LibreOffice choose Tools/Options/View, then select Crystal as the icon style and voila:
