Ah, brings to mind one of my favorite Dijsktra quotes, "Program testing can be used to show the presence of bugs, but never to show their absence!"

I've never understood that to mean that he wasn't in favor of automated testing, only that it's got its limits. In this case, they now know a test case that was missing.

Yup, in my previous gig we had an approach that if there is a bug in the code that the tests didn't catch, it's actually 2 bugs: a product and a test issue. Similarly, if a dev needed to have access to the live debugging session to diagnose the issue, it meant there was yet another bug (to improve debuggability of the product). It was quite nice, taught me a lot.

Indeed. This is why I find 100% unit test coverage can actually be harmful: it gives you an illusion of safety.
