After hitting https://bugs.kde.org/show_bug.cgi?id=506879#c5 nearly 20 times, I realised that the notification, that `plasmashell` provides on `SIGSEGV`, includes a "Restart" button. Clicking that and redoing the steps to crash it consistently causes `coredumpctl` and `abrt` to catch it (although, per https://retrace.fedoraproject.org/faf/reports/1276918/, it isn't always sufficient).
