If there's one thing that gets my goat it's "voodoo debuggers."

There's no actual need to dig into the root cause of a problem if you can blame the new thing you don't understand. Especially when later, after someone competent actually looks into it, the bug turns out to be a change in the old stuff that did it.

If there's two things that get my goat, it's people who fix something caused by human error or negligence and then don't write an automated test to catch it the next time it happens.
