Comment (by QuLogic):

 You are leaking `add_headers` by doing this:
 {{{
 add_headers = g_strdup_printf("SIP-If-Match: %s\r\n%s",
                               sip->publish_etag,
                               add_headers);
 }}}
 Also, in `send_closed_publish`, you introduced `add_headers` again, but
 did not `g_free` it.
