When my code reviewers find bugs, then I know they read my code and understand the intent. When I get approval with no other feedback, I become deeply concerned. For non-trivial changes I let them soak in review for longer than necessary, until I'm unfamiliar enough with it than I feel confident reviewing my own code. I often find bugs this way.
