Очень странная проблема краха rosegarden? [закрыто]

Я облазил весь интернет по поводу этой проблемы, и у всех, похоже, немного другие, но не связанные с моей ошибки.

Вчера Rosegarden работал. Теперь же, каждый раз безошибочно, появляется заставка, намек на окно, но затем область экрана "замирает" и не обновляется (где можно "закрасить" область, перетащив на нее окно ;))

Я пробовал:

sudo apt-get purge rosegarden
sudo apt-get autoremove
sudo apt-get install rosegarden

При вроде бы свежей установке все происходило точно так же.

Вот вывод терминала:

И все. Rosegarden просто зависает. Каждый раз. Я не знаю, что может вызвать какую-то ошибку, которая сохраняется при свежей установке. Кроме того, похоже, что по какой-то причине не удается загрузить ни один шрифт....
