Comment 3 TraceyC 2025-11-13 01:59:54 UTC 
Thank you for the bug report. Based on the backtrace this looks like  bug 509804, except it was supposed to be fixed in Qt 6.9.3 which I see your system is running. I'll let the developers take a look.
Comment 4 Nate Graham 2025-12-08 22:06:41 UTC 
Note that https://qt-project.atlassian.net/browse/QTBUG-139626 doesn't fix this either, as I'm able to reproduce it weekly with Qt 6.10.1.

Comment 7 kde49861515 2025-12-12 11:37:08 UTC 
I've updated to qt 6.10.1-2.fc43.x86_64 and don't seem to be able to reproduce the crash using my old method. Possibly fixed
Comment 8 Nate Graham 2025-12-12 19:27:21 UTC 
Indeed, this was expected to be fixed with a Qt patch, and it looks like the Arch folks have helpfully backported it already!
