I’m using Debian Jessie 8 with XFCE 4 and as usual I purge the LO from the system and install the LO 5.1 from the .deb packages downloaded form the LO website. So after install it a noticed something weird. The icons in the taskbar (or desktop bar) are missing. I try to figure out the config file in /opt/libreoffice to understand but I can’t see what is wrong.
I did a test too: I install the LO from the official repositories, and when both LO 4 and 5.1 are installed in the system the icons are shown correctly. But if I purge the LO 4 again, the problem comeback.
I try the same with MATE Desktop Environment and same problem happens. To exemplify, I put a screen-shot of my desktop, for any help.
Q: Why should I do to fix it?
P.S. sorry for my english.
