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. 1726458 3 dennis.schridde 2018-01-31 17:04:15 +0000 KDE neon User LTS is still at Qt 5.7.1 (5.7.1+dfsg-3+16.04+build16). I filed a request to update KDE neon User LTS to Qt 5.9+, but in case that will be declined: Would it be possible to work-around the issue in KDE? KDE neon can probably more easily ship patched KDE applications than new minor (i.e. not-just-bugfix) versions of Qt libraries. 108979 2017-11-20 14:06:25 +0000 2017-11-20 14:06:25 +0000 New crash
