Hello, I am not sure what I will say does apply here, but you could check: we (users of Ubuntu Lxde or else using Openbox, for instance), regularly have issues with tray icons showing twice or not at all, because of a python script default provided with Openbox, which, imo should be removed upstream. This autostart python script is openbox-xdg-autostart and is called from the openbox-autostart script, located in the same directory of the system (in Archlinux, openbox /usr/lib/openbox/openbox-autostart openbox /usr/lib/openbox/openbox-xdg-autostart in Debian, Ubuntu and derivated, under another directory of the system, such as "/usr/lib/openbox/". From there, either python-xdg (pyxdg) is installed in the system (many programs require it, but not all) and the openbox scripts take care of displaying the icons. Or it's not installed, and the openbox scripts don't display the icons concerned (there are related *.desktop files in the /etc/xdg/autostart directory), and some other mechanism must be provided in order to have theme displayed. For the Bento remix (Ubuntu with Openbox almost standalone), I comment out the faulty line because I use xdg-autostart from the obsession program, but this isn't a clean solution, and I don't like it All in all, the Openbox scripts might need to be removed from the sources upstream, to let the devs of the other programs coming after handle it their way. Don't you think so?
