Welcome to the world of exceptions. Some exception is occurring causing
USC/Mir to crash. However our exception handling is also crashing in
response to that. So we have both no log message indicating what the
error was, and no stack trace indicating where the error was.
If I had to guess though, I would look at removing the proprietary
nvidia drivers. We expect those to fail with Mir/USC for now.
