KDE приложения - пустые окна если запускать в VNC из под su -l other_user

Если в VNC в KDE сессии открыть терминал и зайти другим пользователем, например, user2

то gedit запускается нормально

а kate выдает ошибки типа

QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.
