The crash seems to happen inside of Qt, so it’s an upstream issue :/

Please re-try this with an Qt 6 based release of this year, thanks!

Unfortunately, it's been quite a while since I used Konsole (I ended up switching to another terminal emulator last year for unrelated reasons) and from the original bug report, it sounds like I was never able to consistently reproduce the issue anyway. I don't think there's much I can do to help check whether the problem still exists. Sorry about that!

No problem, thanks for the feedback.
