Bug#969355: cups-browsed.service Hangs on Shutdown

[Jonathan Rubenstein]

Control: severity -1 critical

I am upgrading this bug to critical since it is a bug that halts the 
shutdown procedure, and cups-browsed is rank #1116 on 
popularity-contest's inst rank https://popcon.debian.org/by_inst.gz

Please excuse me if this is an incorrect action.
