Title:
  compiz crashed with SIGSEGV in
  unity::dash::ResultViewGrid::OnKeyNavFocusChange() from
  sigc::internal::signal_emit3 from
  nux::WindowCompositor::SetKeyFocusArea()

Status in Unity:
  Incomplete
Status in “unity” package in Ubuntu:
  Incomplete

Bug description:
  I clicked the "Unity" icon on the launcher, then the Applications icon
  at the bottom. I clicked on "Filter results" then on "Accessibility".
  I then clicked "Customization" and again on "Accessibility" to
  unselect it, then when I clicked on "nn more results" nothing
  happened, but shortly after that, Compiz crashed.

  The package name that apport initially gave for this was 'nux', but I
  think this is a Unity bug since the SEGV happens inside a unity::dash
  method.
