mountmanager открывается только из командной строки, а не из панели запуска

Я больше не могу открыть MountManager из панели запуска. MM запускается из командной строки и функционирует нормально, но останавливается, как показано ниже. Попытался переустановить MountManager, как это было предложено в другой сессии форума, но он ведет себя так же. Также MountManager.log ничего не записывает. Это не страшно, но просто любопытно, может ли это быть симптомом более серьезной проблемы. **

Позже я обнаружил, что смог установить mountmanager через cairo-dock, поэтому проблема с лаунчером может быть больше, чем мм.
