After the todays update all my icons are gone. I remember that one package complained about the icon cache and showed me a command with a redirector (I think it was gtk-update-icon-cache). libgtk2.0-bin wasn't installed at this time and after installing it the command gtk-update-icon-cache hasn't helped me. Has somebody an idea how to fix this? I'm using LXDE and reinstalling lxde-icon-theme hasn't helped too.
