While understanding if of course important, sometimes it's possible to just "zen" the bug. After working with the same codebase for long enough I've been able to see behavior and think, "That's probably down in the login handling code..." and then start there. I don't necessarily have to understand the login code, but it's gnarly, and I've seen similar bugs before from it. I'm right more often then I would expect. When the zen fails it's off to the methods mentioned in the article.
