Thank you for taking the time to report this bug and helping to make Ubuntu better.
Your strace suggests that the process is being killed by a SIGTERM from pid 21284 which is running as root. Can you reproduce again and try to determine which process your SIGTERM is coming from?

It sounds like perhaps your session management is creating a new agent process and killing the old one?
