@jens: Is it still worth reporting wx3.0 crashes? Last evening I spend another few hours with your build - and unfortunately I got so many crashes that it's getting hard to code with it. Especially when doing global global search&replace with many files. I sometimes got several crashes within minutes when refactoring code. Never easy reproducible, but always happening after a working with it a while. And generally getting some asserts first like the one above.
I'd like to help with reports - can also start from console and enable additional output etc if that is possible. But given the amount of crashes I had, I suppose you probably still get them yourself enough anyway. So not sure if it's worth reporting each one currently?
