O ícone docklet Docky não é carregado na inicialização

Question

O ícone do depósito de lixo no Docky parece estar quebrado / não está sendo carregado corretamente após o login. Alguém sabe como posso corrigir esse problema?

Como reproduzir: Sempre que o Docky iniciar automaticamente no login.

Passos para reproduzir:

1. Instalação limpa do Xubuntu 18.04
2. Executar atualizações
3. Instalar o Docky e suas dependências
4. Iniciar o Docky
5. Insira seu menu de configuração
6. Marque a caixa de seleção "iniciar quando o usuário fizer login", se ainda não estiver marcado
7. Reinicie ou faça logout e faça login novamente
8. O ícone do Docklet de lixo está ausente
