I just hit this bug in a xenial-queens openstack when relating to a new ceph cluster (bionic-queens luminous) using ceph-proxy.
Removing the nova-compute to cinder-ceph relation did not remove the libvirt secret.
My workaround was to remove <uuid>.base64 and <uuid>.xml in /etc/libvirt/secrets and also run:
sudo virsh secret-undefine <uuid>
