All talks about bugs, how they were solved, dead ends attempted, tools/techniques used to diagnose, etc.
Would be really useful to see how other people approach debugging and you'd probably get to learn about lots of tools you didn't know existed.
Good debugging stories, like the OP, are mysteries.
