As pointed out on IRC by pinotree, exporting all properties will do
the trick.
I.e. adding
| QDBusConnection::ExportAllProperties
in src/lib/MarbleWidget.cpp   and src/lib/MarbleMap.cpp
exposes them.

Then one can use
  marble_pid="$(pidof marble)"
  alias CALL='qdbus org.kde.marble-${marble_pid} /MarbleWidget'
  CALL org.freedesktop.DBus.Properties.Get org.kde.MarbleWidget latitude
to get the current latitude (or longitude or zoom, etc.).

Note that one has to go through org.freedesktop.DBus.Properties.Get
as this latitude is not a method, but a property.

So with this, all works fine!!

Thanks a lot,
