Web process crash in gdk_event_source_check:

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));
        }

(Full backtrace downstream.)
Comment 2 Michael Catanzaro 2016-11-18 04:49:33 PST 
And the error condition is "broken pipe"
Comment 3 Michael Catanzaro 2016-11-18 05:05:51 PST 
OK, same crash and same error condition in WebKitDatabaseProcess as well. Why are we running GTK+ in the database process???
Comment 4 Michael Catanzaro 2016-11-18 09:06:37 PST 
(Note: 46 reports of this.)
Comment 5 Michael Catanzaro 2016-11-24 06:53:32 PST 
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
Comment 6 Michael Catanzaro 2016-11-25 15:32:48 PST 
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
