Description
В конфигурации программы (r370) параметру "SIP порт" было задано такое значение порта, на котором другая программа уже слушает TCP сокет. В результате программа упала при старте. Вот что вывелось в консоль:

А вот другое падение, так падает чаще всего:

r374.
Причина данного явления в том, что я посылал emit Error_Report и после него ещё деинициализиловал объекты и потом только завершал основную функцию потока Run. Так как деинициализация может занимать достаточно много времени, то главный поток успевал получить сообщение и первым приказать совершить потоку инициализации, пока он работал. Ошибка явео из-за этого и удалось воспроизвести подобную ситуацию.

for help on using tickets.
Вот стэк в месте получения сигнала под отладчиком (падение выглядит немного иначе чем в описании тикета):
