[SailfishDevel] Persistently storing a ListModel

[Marcin Mielniczuk]

Thanks a lot!

So I'm trying to store a pointer to ListModel and ConfigurationValue
drops this silently because it's an invalid value, doesn't it?

What is the standard way in Sailfish to access DConf from C++? I think
about reimplementing the model as a subclass of QAbstractListModel anyway.
