Found a couple more NPE sources. Also, we should indicate to the user when we don't have any data and provide a hint on configuring logging so that we'll get some.

This was caused by trying to inspect the modification time on a null log entry (probably when the instrumentation log is empty). I've added a check for this case that will prevent this problem. Marking as fixed.
