Segfault при запуске после обновления qt до 4.7.4

[GoogleCodeExporter]

 После недавнего обновления библиотеки qt в репозитарии debian wheezy c 4.7.3 до 4.7.4, программа стала давать Segfaultы после прохождения авторизации.

1. Запускаем программу
2. Выбираем аккаунт и авторизуемся
3. Программа сегфолтится

Перекомпиляция не помогла.
