I'm running Ubuntu 15.04 on a Thinkpad T450. I installed numix-circle-theme like that:
sudo add-apt-repository ppa:numix/ppa
sudo apt-get update
sudo apt-get install numix-icon-theme-circle
and used the unity tweak tool to set the icons to numix circle.
Everything looks real nice except my KiCAD icon. It seems as is should be here (https://github.com/numixproject/numix-icon-theme-circle/issues/179) so I investigated and under /usr/share/icons/Numix-Circle/48x48/apps there is a kicad.svg.
So why is is not showing the new circle icon of KiCAD?
cat /usr/share/applications/kicad.desktop
