May be coming from this sanity check: "qFatal("orphan event");" from https://invent.kde.org/pim/ktimetracker/-/blob/master/src/dialogs/historydialog.cpp

You can run ktimetracker from command line to confirm if you want, this should print "orphan event".

The code should be changed to ignore such errors.

Indeed I see "orphan event" in the console.
