Bug with UTF-8 string and dbus

Hi,

While coding notifications.el, I found an odd bug here.
When using it with some UTF-8 chars in a string (like 'title' or
'body'), Emacs raises a D-Bus error because it did not received a reply.
But reading dbus-monitor, it did NOT send a method call.

I can reproduce it easily with:

  (dbus-call-method :session
                    "org.freedesktop.Notifications"
                    "/org/freedesktop/Notifications"
                    "org.freedesktop.Notifications"
                    "Notify"
                    :string "Emacsé")

(this is not a valid call for Notify, but anyhow it should send the
call)

I've tried to break on inside dbus.c:xd_append_arg and what I got is:
492		  char *val = SDATA (Fstring_make_unibyte (object));
(gdb) print (char *) val
$6 = 0x253e830 "Emacs", <incomplete sequence \351>

Is this normal? If yes, how to fix? If no, where's the bug?

Thanks,
