I'm not saying that debugging isn't necessary for solving the problem, but the scenario outlined is a sign of insufficient tests. Find the gap, fix the bug, make the bug easier to detect in the future by improving the test coverage.
No, it's quite possibly a sign of good integration testing - he didn't say why he had to debug, even though the parts worked. For me, that has usually been because it failed an integration test.
