Subject: [PATCH] gdbusmessage: Fix a minor memory leak on an error path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If g_dbus_message_to_blob() fails at all, it will leak its mbuf. Spotted
by running the gdbus-serialization test under Valgrind — so there is a
justification for leak-free tests after all!
