Hi all.
I know that this is not a fully KDE issue, but it has to do with Qt4, so
maybe any of you have some hints. Here it is:

I'm trying to get the response from a dbus call using qt4 dbus module.
I'm able to get a QString reply without problems, but the problems
arrive when this reply is an aggregation of a primitive type (not
QStringList).

For example, if I want to get this:
ivan@masao:~$ dbus-send --system --print-reply --reply-timeout=2000 \
--type=method_call --dest=org.freedesktop.NetworkManager \
/org/freedesktop/NetworkManager +org.freedesktop.NetworkManager.getDevices
method return sender=:1.2 -> dest=:1.28
   array [
      object path "/org/freedesktop/NetworkManager/Devices/ath0"
   ]

I code the following:

QDBusConnection bus = QDBusConnection::systemBus();
QDBusInterface dbus_iface(
                        "org.freedesktop.NetworkManager",
                        "/org/freedesktop/NetworkManager",
                        "org.freedesktop.NetworkManager", bus);
QDBusReply<QStringList> reply = dbus_iface.call("getDevices");

if (!reply.isValid()) {
        qDebug() << "Error: " << reply.error().message() << "(" << \
reply.error().name() << ")"; } else {
        qDebug() << reply.value();
}

... but I always get:
Error:  "Unexpected reply signature" ( "org.freedesktop.DBus.Error.InvalidSignature" \
)


It seems that the problem is that call() method is not returning a QStringList \
DBusReply. So I've changed it to QDBusVariant, QString, QDBusObjectPath ... but no
success.

Any hints??

Thanks in advance!!!
