how to free the memory got from dbus_message_get_args() ?

[falls huang]

Hello!

    I'm new to dbus, and I have searched the mailing list but couldn't
find  any similar problem .  My linux box version : ubuntu(dapper)  ,
dbus(0.60)

    If I uncomment either of  "free(s)" or "dbus_free(s)" ,   the
program will crash .
But if I don't free , there'll be a memory leal.

How can I fix this problem ?

The code is below :

    char *s;
    dbus_error_init (&error);

    if (dbus_message_get_args
       (message, &error, DBUS_TYPE_STRING, &s, DBUS_TYPE_INVALID)) {
             g_print("Ping received: %s  %x\n", s, s );
             //free(s);
           //dbus_free (s);
    } else {
           g_print("Ping received, but error getting message: %s\n",
error.message);
           dbus_error_free (&error);
    }
