-- Information about the crash:
Simple steps to reproduce:
1. Add System Monitor widget
2. Open config dialog (Appearance page tab)
3. Click "Load Preset…" button (NB: the dialog is super tiny)
4. Close the config dialog window with the preset dialog overlay open -> boom
This report is from Fedora packages, but the same thing happens on master (but
my drkonqi there is broken and fails at doing the backtrace).
Looks like the destruction order is wrong and the Popup tries to access already
destroyed things.
I originally noticed this while trying ot fix the tiny dialog (which is due to
Kirigami.Dialog magic), but my attempts to fix this also caused slightly
different (and even more easily triggered) crashes.
The crash can be reproduced every time.
