+Subject: [PATCH] (dyn|multi)udpsink: unbreak on !IPv6 systems after 130268bc
+ (Bind socket before using it)
+
+The g_socket functions only touch the error argument on errors, so clear
+err back to NULL in case g_socket_new (G_SOCKET_FAMILY_IPV6) failed, as
+we check for err != NULL later on to know if g_socket_bind() failed,
+otherwise we errously fail on systems without IPv6 support.
