-- Information about the crash:
In order to test a website's adherence to `color-scheme: light dark`, I
manually switched from `org.kde.breezedark.desktop`, applied by the automatic
colour switcher, to `org.kde.breeze.desktop`, then back, in reasonably quick
succession.
Considering https://bugzilla.redhat.com/show_bug.cgi?id=2563697#c15, I am
surprised that Konqi has traces. If not for that, I would also provide a RedHat
Bugzilla ticket.
The crash can be reproduced sometimes.
