It appears the fix is in Ubuntu 20.04 but not 18.04. So I will mark this
to request a fix in 18.04.

Since upgrading from 16.04.5LTS to 18.04.1LTS last Thursday my syslog
has been filling with the below:
Aug 19 11:34:11 localhost gnome-shell[2503]: Object Meta.Background
(0x7febd401a470), 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

Following suggestions in previous bug reports about this I went
through and removed all of my shell extensions:
