Update: The django code clearly has a bug, and I fixed it on my system. That allowed me to see the next higher up error, which was an error importing one of my own context_processors. This is odd, as the file and function are there, and are readable, and if they were not I would always get this error, not just get it intermittently. I still think there is another higher up error, and I tried to find it by setting a breakpoint and running the devel server, but with that the error never occurs.
