KRunner crashes when screen layout changes during login

When starting KDE Plasma on a laptop in a docking station with two monitors attached the krunner process crashes with the attached backtrace. In my case the problem appears every time I start KDE with the laptop docked. When the laptop starts undocked with just the internal screen no crash happens.

The system has KScreen installed and configured.

According to https://bugs.kde.org/show_bug.cgi?id=353129 the crash seems to be reported by other users in similar environment.

A brief analysis would indicate that QQuickScreenAttached::screenChanged() is trying to disconnect all signals from the old screen. Unfortunately the old screen instance seems to have been destroyed already. This causes QObject::disconnect() to die while calling a virtual method on it (see bottom of backtrace).
