Title:
  gdm crashed with SIGSEGV in g_main_context_dispatch()

Status in gdm package in Ubuntu:
  New

Bug description:
  Problem 1: When logging out of a user account, gdm presents the gray
  screen with the top bar, but no greeter. The system is locked up, no
  cursor. Can't even bring up a VT. The only time I see the greeter is
  once, at boot.

  Problem 2: Tried to log in with the Wayland Gnome session, but the
  screen just flickered and came back to the greeter. So I tried the
  regular Gnome session, resulting in a black screen. This time I was
  able to get a VT, from which I restarted gdm. This time I was able to
  log in to the regular Gnome session, but with the error message you
  see.
