This message is from tdelibs/kinit/kinit.cpp. They appear in the xession log.

I don't mind the messages and I can see from the source code they are intended to be debugging aids.

But they lack information. How do I add the process name to the message?

Like this:

PID 10804 (process name) terminated.

With that information the message might remain useful only for debugging, but at least the message appears more useful and informational to users.
