nautilus crashed with SIGABRT in g_assertion_message()

I was installing Steam in the background via terminal, searching for documentation on creating extensions for Nautilus, and waiting for a Backup to complete to my NAS (deja-dup) when the computer spontaneously rebooted. I've never experienced something like this from normal usage (though I've caused such behavior deliberately before) so it took me by surprise.

btrfs seems to have the full file system in tact, though I'm still verifying file hashes via tripwire now.
