When running gnome-shell, the org.gnome.Shell.desktop ID logs this stacktrace to syslog quite often:
Object St.Widget (0x557f6eb1c7d0), has been already deallocated - impossible to access to it. This might be caused by the fact that the object has been destroyed from C code using something such as destroy(), dispose(), or remove() vfuncs
