    process 5697: arguments to dbus_message_new_method_call() were incorrect, assertion "destination == NULL || _dbus_check_is_valid_bus_name (destination)" failed in file ../../../dbus/dbus-message.c line 1370.
    This is normally a bug in some application using the D-Bus library.
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
      File "/home/ldo/projects/dbussy/dbussy.py", line 3473, in new_method_call
        raise CallFailed("dbus_message_new_method_call")
    dbussy.CallFailed: dbus_message_new_method_call failed

Seems like libdbus prints a message, but does not abort.

So at the API level, you get back a failure indication without any hint
as to what actually was wrong.
