Comment 3 Nate Graham 2025-01-03 22:14:29 UTC

Backtrace is all in Qt; no KDE code implicated so far. The Qt version is somewhat old too.

https://crash-reports.kde.org/organizations/kde/issues/71020/events/7d704112fc334f5087e3ac41138c7959/?project=9 shows that this is the only such crash in 30 days. Let's track it there.
