I have a fix for the exception. I am currently investigating whether logging in the dbus service works at all. As far as I can tell there is no reason (with my fix) the desired log message should not be written to /etc/rhsm/rhsm.log but yet it is not. Furthermore, I've not seen any log messages coming from the dbus service. I will continue investigation. I have employed the same logic as is done in rhsmd, applied to the dbus services. The PR with the both fixes necessary for this bug has been attached as an external tracker to this bug. Verifying Version....
