New crash information added by DrKonqi

konsole (21.04.0) using Qt 5.15.2

- What I was doing when the application crashed: on a remote SSH session to AWS EC2 server. Pressed 'ctrl+c' during command requiring  sudo privileges. I forgot to actually use sudo, so it asked for password.

This is an upstream bug in Qt which was fixed with https://codereview.qt-project.org/c/qt/qtdeclarative/+/371842. It will be backported to the KDE patch collection soon; see https://invent.kde.org/qt/qt/qtquickcontrols2/-/merge_requests/3

Thanks so much to Nicolas Fella for discovering this and backporting it!
