Comment 6 for bug 1464335

Ah. From /var/log/syslog:

  Jun 17 13:08:21 ... rsyslogd-2040: can not read file '/home/esnow/.juju/local/rsyslog-cert.pem' [try http://www.rsyslog.com/e/2040 ]

So the new location *is* causing a problem on local provider. The rsyslog user cannot reach the file due to the permissions on ~/.juju.

Now back to how to get it to work...
