[Pkg-utopia-maintainers] Bug#935398: dbus: DBus error: org.freedesktop.DBus.Error.TimedOut: Failed to activate service 'org.bluez'

[skyguide]

Package: dbus
Version: 1.12.16-1
Severity: normal

Syslog is flooded with error messages regarding failed attempts to activate a bluetooth service on a system with NO bluethooth hardware:

Aug 22 13:37:10 dbus-daemon[523]: [system] Activating via systemd: service name='org.bluez' unit='dbus-org.bluez.service' requested by ':1.129' (uid=0 pid=503 comm="/bin/brltty --no-daemon ")
Aug 22 13:37:10 systemd[1]: Condition check resulted in Bluetooth service being skipped.
Aug 22 13:37:35 brltty[503]: DBus error: send message: org.freedesktop.DBus.Error.TimedOut: Failed to activate service 'org.bluez': timed out (service_start_timeout=25000ms
Aug 22 13:37:35 brltty[503]: brltty: DBus error: send message: org.freedesktop.DBus.Error.TimedOut: Failed to activate service 'org.bluez': timed out (service_start_timeout=25000ms
Aug 22 13:37:43 dbus-daemon[523]: [system] Activating via systemd: service name='org.bluez' unit='dbus-org.bluez.service' requested by ':1.129' (uid=0 pid=503 comm="/bin/brltty --no-daemon ")
Aug 22 13:37:43 systemd[1]: Condition check resulted in Bluetooth service being skipped.

Please advise how to stop DBus generating these error messages. 
Again - system has no bluetooth hardware installed. 
Attempts to stop/disable a bluetooth services with systemd did not stop dbus from spamming logs with these error messages.
