Can I run a systray theme while the kicker systray is running?
It’s better not to. If you run a theme with a SysTray on it while a regular kicker systray is running, the theme will “steal” all the icons from the first systray. This is because in KDE and Gnome, the systray icons are really little windows and there is only one copy of each running. If you want to run a systray theme, you can remove the systray from kicker.
