Thank you for reporting!

We have several bug reports involving QSortFilterProxyModels:

https://bugs.kde.org/show_bug.cgi?id=360817
https://bugs.kde.org/show_bug.cgi?id=361895
https://bugs.kde.org/show_bug.cgi?id=362308
https://bugs.kde.org/show_bug.cgi?id=363805
https://bugs.kde.org/show_bug.cgi?id=378283

There are other reports outside KDE PIM, too, that involve Qt <5.8 and QSortFilterProxyModels. As far as I can see, they all involved Qt before version 5.8. I think the crashes were caused by these Qt bugs:

https://bugreports.qt.io/browse/QTBUG-44611
https://bugreports.qt.io/browse/QTBUG-32981

I am not entirely sure if those Qt bugs are actually the culprit, so I won't mark the above bugs as duplicates of each other.

If this crash still happens with a Qt version greater than 5.8, please drop a note and this bug is reopened. You should include a more recent trace and Qt/Kontact versions then.
