It's crashing on this error condition:

      if (source->pfd.revents & G_IO_IN)
        {
          if (wl_display_read_events (display_wayland->wl_display) < 0)
            g_error ("Error reading events from display: %s", g_strerror (errno));
        }

And the error condition is "broken pipe"

OK, same crash and same error condition in WebKitDatabaseProcess as well. Why are we running GTK+ in the database process???

(Note: 46 reports of this.)

Looks very similar to this gnome-terminal crash when the user logs out of GNOME (i.e. when the Wayland display goes away): https://bugzilla.redhat.com/show_bug.cgi?id=1395389

Looks like it affects a bunch of other GTK+ applications:

I doubt it's our bug.

Ahhh, turns out this is just the infamous https://bugzilla.redhat.com/show_bug.cgi?id=1366897
