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.
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.

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.
