I see from googling to:
https://svn.cronos.be/svn/deconf/deconf-desk/trunk/frontends/dbus/dbus-shared.c

That they use code similar to what I'm trying to do.

I changed the dbus_message_iter_get_array_len call to use &subiter as
its parameter, not the parent (of type DBUS_TYPE_ARRAY, signature 'as').

However, you will see from the output below, that it returns "54", not
"2". Is it returning the byte count of the array? I make that about 45,
including null terminators. Am I doing something stupid here?
