As workaround to get the app working you can manually edit '/var/lib/apparmor/profiles/click_com.ubuntu.calendar_calendar_0.4.latest'

dbus (receive, send) bus=session interface=org.gnome.evolution.dataserver.Calendar peer=(label=unconfined),
After save it run: sudo apparmor_parser -r /var/lib/apparmor/profiles/click_com.ubuntu.calendar_calendar_0.4.latest
