Nathan, it is a different backtrace. This is not caused by QSGRenderLoop::handleContextCreationFailure(), but by KIO code.
My mistake. I'm still not so good at interpreting these.
Testing with Thunderbird 52.5.0, Gwenview 17.12.0 and Frameworks 5.40, this works fine for me. I suspect this has been fixed in KIO at some point, because I cannot reproduce and the bug says it should be reproducable every time. Nevertheless, please test again on a newer system and comment if it still crashes for you, then we'd need to reopen.
