Public bug reported:

If you push a document that contains property being a list of strings,
like:

{
  'attachements': ["/path/to/foo1.png", "/path/to/foo2.png"]
}

Retrieving it is making the attachements a ListModel through the QML
type system (outside of u1db's scope thus). The ListModel contains
ObjectModel and it's useful to attach that to Repeater/Grid.

However, when we try to store those data back (from the same object), the ListModel/ObjectModel aren't storable in u1db, so we end up with:
{
  'attachments: [null, null]
}

So getting the object don't enable to save it back, we have to manually
typecast it and create some json objects from it, which is quite ugly
and cumbersome:

#diff-63dd6639b235200e552147bf0a9003b8R59.

Any idea if u1db-qt can typecast it back to something that can be
stored, or anything to make the developer's life easier?
