First of all, you need to get rid of the spaces. The type is "(a((ay)s)q)"

struct InnerInnerType
{
    QByteArray data;
};

struct InnerType
{
    InnerInnerType data;
    QString str;
};

struct OuterType
{
    QList<InnerType> list;
    ushort value;
};

Q_DECLARE_METATYPE(InnerInnerType)
Q_DECLARE_METATYPE(InnerType)
Q_DECLARE_METATYPE(OuterType)

Then write the streaming operators for all three types:

QDBusArgument &operator<<(QDBusArgument &arg, const Type &t);
const QDBusArgument &operator>>(const QDBusArgument &arg, Type &t);
