Git commit 26694e8c82562eac2fdbdb6fa85f56b27fca82a0 by David Faure. Committed on 30/06/2022 at 14:32. Pushed by dfaure into branch 'release/22.04'. Fix crash when clicking on dismiss, sometimes. client->dismiss(this) ends up setting client to nullptr, so the disconnect() warns about null receiver and doesn't actually disconnect. (This is similar to 24f3853f14ec in master) Related: bug 455472, bug 455369, bug 455258, bug 455583 M +1 -1 reminder-daemon/alarmnotification.cpp https://invent.kde.org/pim/akonadi-calendar/commit/26694e8c82562eac2fdbdb6fa85f56b27fca82a0
Created attachment 150577 [details] New crash information added by DrKonqi kalendarac (5.20.3) using Qt 5.15.5 After login I receive a bunch of calendar event notifications. When I click "dismiss" on them, kalendarac crashes. When I restart kalendarac through drkonqi, the notifications appear again. When I click "dismiss" again, kalendarac does not appear to crash again. -- Backtrace (Reduced): #4 0x00007feacc46c910 in QUtf8::convertFromUnicode(QChar const*, int) () from /usr/lib64/libQt5Core.so.5 #5 0x00007feacc2e39d6 in QString::toUtf8_helper(QString const&) () from /usr/lib64/libQt5Core.so.5 #6 0x00007feaccda3e8b in KConfigBase::isGroupImmutable(QString const&) const () from /usr/lib64/libKF5ConfigCore.so.5 #7 0x00007feaccdab976 in KConfigGroup::KConfigGroup(KConfigBase*, QString const&) () from /usr/lib64/libKF5ConfigCore.so.5 #8 0x0000559cbe84d860 in KalendarAlarmClient::removeNotification(AlarmNotification*) ()
