was able to log in though.

Title:
  gnome-screensaver crashed with SIGSEGV in g_main_context_dispatch()

Status in “gnome-screensaver” package in Ubuntu:
  Confirmed

Bug description:
  Opening a new bug because this seems to be the first Oneiric beta1
  instance of the bug. I run gnome-shell, and I was unable to log back
  in after the screen locked. Running gnome-shell --replace from a
  virtual terminal allowed me to unlock the screen. I don't believe it's
  a security issue because I still was required to enter a password to
  get back to my session.
