Значок Docky docklet не загружается на запуске

Мусор docklet значок в Docky, кажется, повреждается/не, загружаясь правильно после входа в систему. Кто-либо знает, как я могу устранить эту проблему?

Как воспроизвести: Каждый раз, когда Docky автоматически запускает при входе в систему.

Шаги для репродуцирования:

1. Чистая установка Xubuntu 18.04
2. Выполните обновления
3. Установите Docky и его зависимости
4. Запустите Docky
5. Введите его меню конфигурации
6. Отсчитайте, "запускаются, когда пользователь входит в систему" флажок, если он уже не отмечается
7. Перезапустите или выйдите из системы и войдите в
8. Мусор docklet значок отсутствует
