Public bug reported:
On system boot, syslog is filled with messages of the form:
Object St.BoxLayout (0x55736a43df40), has been already deallocated -
impossible to connect to signal. 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
Object St.Label (0x55736a684930), has been already finalized. Impossible
to set any property to it.
followed by stack traces
followed by more messages of the form
Object St.Label (0x55736a684930), has been already finalized. Impossible
to set any property to it.
These seem to relate to specific resource:///... extensions such as
ubuntu-doc, openweather-extension, and so on.
There are also assertions that fail of the form
clutter_layout_manager_get_child_meta: assertion
'CLUTTER_IS_LAYOUT_MANAGER (manager)' failed
