I need help with QDBusArgument unmashalling

wincc

I am trying to unmarshall the QDBusMessage message into data now i am stuck at how to get the "internal" struct data, I can not find any example whatsoever online,

with the Mount struct below I get the first 10 but how do I get the next? I am out of things to try.

Output from dbus-monitor type=signal interface="org.gtk.vfs.MountTracker"
