--- Comment #1 from Bharadwaj Raju <bharadwaj.raju...@protonmail.com> ---
Interestingly the base is 0x0 in lookupScopeObjectProperty, is that normal?
Anyway, from some poking in GDB it appears that the file it happens in is
"kcm/kcm_powerdevilprofilesconfig/ComboBoxWithIcon.qml", line 28, which is:
const modelIndex = model.index(currentIndex, 0);
I guess the model is being freed while the page gets unloaded, and sometimes
that results in a call to freed memory?
