Title:
   gnome-shell crashed with SIGSEGV in meta_surface_actor_get_texture()
  from meta_wayland_actor_surface_real_sync_actor_state()

Status in gnome-shell package in Ubuntu:
  New

Bug description:
  See also bug 1859259.

  I had to open a new bug because apport-cli doesn't let me update a bug
  with a new crash report.

  This crash occurred as I started Firefox Nightly on my machine with a
  fairly large session being restored.

  GNOME logged me out as the windows were being spawned by session
  restored.

  My Firefox is being started in pure Wayland mode --
  MOZ_ENABLE_WAYLAND=1

  Based on the feedback I got from Daniel van Vugt (vanvugt), I went
  ahead and disabled all of my extensions *and* removed the named
  extensions Daniel mentioned.

  The crash occurred after I logged out and logged back in after the
  extensions were removed, so I'm hopeful there is something interesting
  to see here.
