dbus-daemon: Rejected send message

Since my Ubuntu laptop upgrade to 9.04 I'm seeing the following messages every 10 minutes in /var/log/auth.log and in my logwatch emails:

dbus-daemon: Rejected send message, 1 matched rules; type="method_call", sender=":1.36" (uid=1000 pid=3697 comm="/usr/lib/indicator-

applet/indicator-applet --oaf-a") interface="org.freedesktop.DBus.Properties" member="Get" error name="(unset)" requested_reply=0 destination=":1.1421" (uid=0 pid=22921 comm="/USR/SBIN/CRON ")): 1 Time(s)

Poking around the net I found this bug and in particular this comment. I applied the suggested fix:

# cd /etc/dbus-1
# cp system.conf system.conf.orig
# vi system.conf
# diff system.conf.orig system.conf

> send_member="Get"/>

After that I tried restarting dbus ('/etc/init.d/dbus restart') but that resulted in logging me out, so I suggest just rebooting instead.
