Bug#837895: Similar bug on strtetch

[Roger James <roger@beardandsandals.co.uk>]

I am seeing a similar bug on stretch. This bug also reports a problem in 
running upstart. However upstart is not installed on stretch by default as 
it is running systemd. The default for the autoconf variable 
enable_indicator_services_command is "upstart --user --startup-event 
indicator-services-start". This will always fail. The package needs to be 
built without this bring enabled to stop this happening.
