@trisha02 do the following, the same thing happened to me.

After you have installed the patch you should have this file "/etc/event.d/dbus-scripts-session"
use an editor like vim or leafpad to edit the file and replace what there with this;

description "dbus-scripts"
author "Graham Cobb <g+770@cobb.uk.net>"

start on started dbus
start on started dbus-actdead
stop on stopping dbus
stop on stopping dbus-actdead

console none

exec /usr/sbin/dbus-scripts --system

respawn

everything should work after that
edit: remember to reboot
