In the debugger, is there a way to break on any exception from namespaces following a pattern?
Interesting idea, I don't think there's a good way to achieve that right now. You could do it based on the class, but identifying which namespace certain classes come from is difficult. The Cursive debugger integration does do that already though, so it might be possible.
You could try playing around with the class filters, and matching the mangled names, depending on how dirty you're willing to get your hands.
