I started two programs: Glipper 2.4 and ClipIt 1.4.2 in my Gnome 3.12.0 desktop on Debian Linux 8. They are in Gnome tray.
Now I click ClipIt menu and choose "Quit". I also kill Python process running Glipper:
$ ps x
4033 ? Sl 0:00 /usr/bin/python /usr/bin/glipper
$ kill 4033
But after I log out and back log in or even when I reboot my computer, these programs appear in Gnome tray again.
I want to remove them persistently, so that they don't appear after logout/login. How?!
