Гном-строитель падает при попытке открыть проект

Когда я пытаюсь открыть проект в gnome-builder запускается ли он нажатием на один из проектов на этом экране (я поместил большой черный ящик над некоторыми более личными вещами):

Или если я использую New кнопку и выберите уже существующий проект, он просто закрывается. И в течение времени, когда я запустил приложение, я получал эти ошибки в Терминале:

И когда я прошу его открыть проект, он существует с этим последним сообщением об ошибке:

22:15:39.0312               gb-greeter-window[13410]:  WARNING: Typelib file for namespace 'Ggit', version '1.0' not found

Так что я просто делаю что-то не так или это ошибка, о которой я должен сообщить?
