Hi Reid Wahl,

Sorry, we use pacemaker in the reproduction environment, which is not easy to upgrade. Is there any way to avoid this bug?

From the source code, it is possible that the function of "dbus_message_get_args" does not get "path".  What are the possible reasons? Is it possible to modify the RA file or other configration files to avoid this problem?
