Bug Description

I have jackdbus running successfully (via qjackctl) in Kubuntu 16.10 with a Scarlett 18i8 USB interface.

If I turn the interface off, jackdbus will usually (not always -- I think I may need to have played audio at least once?) jump to 100% CPU usage (of a single core) and stay there indefinitely.

I can kill the jack processes, turn the interface back on, and restart the processes, and things are fine again.

When the CPU usage happens, I see so further output in .log/jack/jackdbus.log

Judging by jackdbus.log, I think I have "Controller" version 1.9.11:

Tue Dec 27 01:52:41 2016: Controller activated. Version 1.9.11 (unknown) built on Sat Sep 17 05:04:38 2016
