Obviously Logos wasn't completing sitting idle. I had been repeatedly rebuilding a personal book. The book had successfully built, perhaps a minute before the crash, and I was not even using Logos when I noticed the crash popup displayed. Here are the Logs:

I believe this is the salient entry in the error log is:
