Title:
  rsyslogd crashed with SIGSEGV with juju-local configuration

Status in juju-core package in Ubuntu:
  New
Status in rsyslog package in Ubuntu:
  New

Bug description:
  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.
