Bug description:
  According to
  https://errors.ubuntu.com/problem/bcb050f97778eb836056c1c48139bcde30ed0bcb
  it seems to be common-ish.

  This happens when unity8-dash can't find unity8 (mir server) and
  crashing (via QFatal) is our controlled way of exiting (not very
  clean, but it is how it is)[1].

  This will happen for example if you try to start unity8-dash directly (not 
through upstart) from a ssh shell in the phone, i.e
  phablet-shell
  stop unity8-dash
  unity8-dash

  And it may happen after a unity8 crash.

  In general we think that it's not a pressing issue users have since
  there seems to have not been any report of unity8-dash failing to
  start, but we're creating this bug to track it from time to time and
  make sure it doesn't get worse.

  [1] Qt platform plugins (also know as QPA) don't have a way to say
  they had a problem initiating themselves, Qt code is prepared for the
  QPlatformIntegrationPlugin::create() function to return, but all it
  does when that happens is call qFatal anyway [2]
