Пинта устанавливает, но не загружает графический интерфейс

Программа рисования Pinta устанавливается из Центра программного обеспечения, но не загружается из значка средства запуска, или из значка папки приложений или терминала.

Я использую Ubuntu 12.04 на двухъядерной машине Intel Atom с 2 гигабайтами оперативной памяти и графикой Nvidia Ion, используя драйвер Nvidia.

Вывод pinta:
