Ошибка Wireshark при запуске захвата

Я использую Wireshark на Ubuntu 14.04 LTS, и он у меня работает. Однако, когда я нажимаю кнопку "Пуск" после выбора интерфейса, программа зависает. Я попытался "экспортировать LIBOVERLAY_SCROLLBAR=0" безрезультатно. Я запустил его в терминале, и это то, что я получил, и, как вы можете видеть, ошибки просто повторяются, пока я не заставлю программу закрыться:
