Sorry to take so long. No, I am not using Latte Dock. Thanks.
Comment 4 Nate Graham 2021-10-15 15:49:20 UTC 
OK, thanks.
Comment 5 Nate Graham 2023-12-09 04:20:23 UTC 
It looks like the backtrace is entirely in Qt, and there have been a lot of Qt versions since this crash was reported. Are you still able to reproduce it in Plasma 5.27?
