The debug symbol was missing so the information is less useful, but I notice you are using KDE Neon which may suffer from old X11 version, and the bug may be already fixed in the latest X11.

Git commit d9d2c8b3c33bfea93080b5104503a4c6333d7558 by Harald Sitter.
Committed on 12/02/2024 at 11:22.

resultmodel: guard model in threaded resource cleanup

this previously was subject to a race condition between ResultModel
destruction and the file access finishing. When the file access took
long enough the Model would have been deleted leading to a crash.

Instead weakly point to the model via the QObject such that we can then
check if still exists by the time we want to call into it
Related: bug 466995
Fixes PLASMA-WORKSPACE-YZ

Hi.

I have decided not use KDE  anymore as I've had trouble installing it of
late. Thank you for your time.
