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

[Dan Letzeisen <dtl131@gmail.com>]

Package: cups-browsed
Version: 1.28.1-1
Severity: normal

Recently, my system has taken a while to shut down. From the log, it
looks like cups-browsed is taking the maximum 90 seconds to try and
stop/sigterm (and still fails, resulting in sigkill).

Aug 29 14:39:41 hostname avahi-daemon[648]: Disconnected from D-Bus,
exiting.
Aug 29 14:41:09 hostname systemd[1]: cups-browsed.service: State
'stop-sigterm' timed out. Killing.
Aug 29 14:41:09 hostname systemd[1]: cups-browsed.service: Main process
exited, code=killed, status=9/KILL

This began earlier this week, probably upon upgrade to
cups-filters/browsed 1.28.x
Another Debian sid user confirmed the issue occurs for them.

If there is more information I can provide, let me know. Thanks.
