[Bug 1319897] Re: gnome-shell crashed with SIGABRT in g_assertion_message()

[Tim]

Marius, given you have already test the patches against 3.12, it should
be enough to make sure they apply cleanly to 3.10 packages and build ok
(use pbuilder or sbuild).

Once we SRU it back into trusty it will need testing though..

  gnome-shell crashed with SIGABRT in g_assertion_message()

Bug description:
  This happened on resume from S3 sleep.  It seems related to multi-
  monitor support: I had an external display connected via VGA that I
  unplugged at around the same time as I suspended the laptop.  The
  external display was unplugged when I woke the laptop up.

  There was a long pause with a blank screen before gnome-shell crashed
  and restarted (I've observed that pause in other gnome-shell crashes
  too; maybe it's just apport taking a long time to process the core
  dump?  dunno).  It then restarted, flashing the picture of my desktop
  before restoring the lock screen (this could have privacy/security
  implications).

  Bug 1190535 might be a duplicate; I can't tell.  The stack trace in
  that bug seems mangled.

  FWIW the crash was a SIGABRT due to

    assertion failed: (n_outputs == config->n_outputs)

  which was visible in the function arguments passed to
  g_assertion_message() in the stack trace shown by apport before I
  submitted this bug.  I don't trust the retracer bot not to mess up the
  stack trace like it usually does for PPA packages.
