I told you i don't use evolution and deskbar-applet
so i have removed them
$sudo apt-get remove contact-lookup-applet deskbar-applet
Deskbar-applet is intended as a browser-like keyword-driven url bar.
You type a web address, or an email address, or a file name, or some
keyword then the arguments, and it shows a popup with possible choices
from there. Like 'Search google for foo'.
