Public bug reported: It started to happen after I upgraded from Ubuntu 13.04 to 13.10. Gnome freezes (but mouse cursor keeps moving) at least once a day and only Gnome restarting helps. When this happens the following error can be found in the /var/log/syslog: Nov 6 14:30:41 ayakhno-pc gdm-simple-slave[5992]: GLib-GObject: g_object_ref: assertion 'object->ref_count > 0' failed Nov 6 14:30:41 ayakhno-pc gdm-simple-slave[5992]: Child process 6237 was already dead.
