[Bug 1534106] [NEW] rsyslogd crashed with SIGSEGV with juju-local configuration

[Martin Pitt]

Public bug reported:

installing juju-local pulls in rsyslog (at least on current xenial).
When doing

- juju init
- edit ~/.juju/environments.yaml to set "local" as default
- juju boostrap

this creates a file /etc/rsyslog.d/25-juju-USERNAME-local.conf and
restarts rsyslog. rsyslog then crashes like this with this
configuration.
