Бойко-очень важный: g_environ_setenv: утверждение 'значение! = ПУСТОЙ УКАЗАТЕЛЬ', отказавший - попросил входить в систему дважды

Что-то не так с моей сессией гнома?

Я включил свой компьютер, вошел в систему, ожидал некоторое время (10-20 секунд) и затем попросился войти в систему снова. Во второй раз это работало, но по левую сторону судна попросило, чтобы я сообщил о проблеме.

Вот набор ошибок из моего системного журнала с того промежутка времени:

Я предполагаю, что самые интересные/релевантные ошибки/предупреждения являются теми из ядра. В частности, посмотрите на отказ сегментации. Можно ли видеть что случилось с моей машиной?
