Not a very good backtrace, but it happens when I close the Konsole window that was responsible for the notification before the notification is closed. So the d-pointer is not null, but invalid, so the null-check in KNotification::id() is not enough. Might want to make the d-pointer something other than a bare pointer. #0 0x00007f77e8860329 in KNotification::id() () from /usr/lib/libKF5Notifications.so.5 #1 0x00007f77e88645cc in ??
