[РЕШЕНО] Падает plasmashell

Calculate Русский

После обновления начала падать plasmashell. После ввода пароля в окне входа остается только черный экран. Запустить приложения получается только через alt-F2.
Вот выхлоп plasmashell если её запустить повторно. Я никак не пойму что из этого критичная ошибка:

пробовал вернуть прежнюю версию plasma-desktop, ошибка сохраняется.
Посоветуйте в чем может быть проблема?

проблема оказалась в кеше плазмы. Почистил папки связанные с плазмой в ~/.cache/ и все запустилось без падений.

Bug #879

Выходит ошибка:

Временное решение:
Yes, but dbus doesn’t seem to be the (main) culprit here, so e-emerging is not even necessary. To get an immediate fix, use Egor’s

prelink -u /usr/lib64/libdbusmenu-qt.so.*

To get a more permanent fix, use Alexander’s

echo ‘-b /usr/lib64/libdbusmenu-qt.so*’ >> /etc/prelink.conf.d/dbus.conf

I can confirm the former works; the latter is just making this permanent, i.e., meaning that the next (daily) prelink run will not mess things up again.
