[sisyphus] Segfault in kded5

[Maxim Vetsalo]

Добрый день!

Система - полностью обновленный сизиф. После недавнего обновления (замечено было в четверг) стал пропадать индикатор раскладки клавиатуры из системного трея. После старта системы он виден секунд 20, а потом исчезает. Если сделать в терминале:

     qdbus org.kde.kded5

то он опять появляется секунд на 5-10 и снова исчезает. При этом (не всегда) выползает уведомление о сбое в kded5. Переключение раскладок при этом работает. 

В логе:
