On ejecting a DVD I got

Error getting props: "org.freedesktop.DBus.Error.InvalidArgs" "No such
interface “org.freedesktop.UDisks2.Filesystem”" for
"/org/freedesktop/UDisks2/block_devices/sr0"
ASSERT: "dev->backendObject() != nullptr" in file
/local/hdd/gebhard/kde/src/frameworks/solid/src/solid/devices/frontend/devicemanager.cpp,
line 234

I would propose to relax the code


void Solid::DeviceManagerPrivate::_k_deviceRemoved(const QString &udi)
{
    if (m_devicesMap.contains(udi)) {
        DevicePrivate *dev = m_devicesMap[udi].data();

        // Ok, this one was requested somewhere was valid
        // and now becomes magically invalid!

        if (dev) {
            Q_ASSERT(dev->backendObject() != nullptr);
            dev->setBackendObject(nullptr);
            Q_ASSERT(dev->backendObject() == nullptr);
        }
    }

    Q_EMIT deviceRemoved(udi);
}
