Bug#713915: jackd2: no longer starts

[Jamie Heilman]

Package: jackd2
Version: 1.9.9.5+20130622git7de15e7a-1
Severity: important

For some reason, with the upgrade from
1.9.8~dfsg.4+20120529git007cdc37-5, jack_control start no longer
works, and I get this:

Without having delved into it in any detail, it looks like the new
build doesn't interpret my config correctly.  My conf.xml is:

<?xml version="1.0"?>
<!--
JACK settings, as persisted by D-Bus object.
You probably don't want to edit this because
it will be overwritten next time jackdbus saves.
