Created attachment 134908 [details] New crash information added by DrKonqi kontact (5.13.3 (19.12.3)) using Qt 5.12.8 - What I was doing when the application crashed: I don't know if all of the actions below are relevant to the crash, but I'll mention them for completeness: 1. I use KMail via the Kontact app. 2. I read a few messages in my Inbox, and moved a couple of them to other folders. 3. I individually refreshed the Inbox and also these other two folders. 4. I replied to one email in one of the other folders. 5. After the email was successfuly sent, I refreshed that folder as well as the Sent folder. 6. I closed Kontact. 7. Kontact crashed. Also, as an aside my email is hosted on KolabNow and I configured KMail to access it with the Akonadi Kolab resource. My backtrace isn't identical to the one in this report, but almost. I would wager it's the same issue. Unfortunately the Ubuntu crash tool tells me there are no debuginfo packages I can install to improve the quality of the backtrace. These are the stock KDE packages from Ubuntu. At the moment they are the latest version available. -- Backtrace (Reduced): #6 0x00007f9f7d008e05 in KMReaderMainWin::~KMReaderMainWin() () at /lib/x86_64-linux-gnu/libkmailprivate.so.5 #7 0x00007f9f7d008edd in KMReaderMainWin::~KMReaderMainWin() () at /lib/x86_64-linux-gnu/libkmailprivate.so.5 #8 0x00007fa04cc9fb74 in QObject::event(QEvent*) () at /lib/x86_64-linux-gnu/libQt5Core.so.5 #9 0x00007fa04d6ce25d in QWidget::event(QEvent*) () at /lib/x86_64-linux-gnu/libQt5Widgets.so.5 #10 0x00007fa04d7e3148 in QMainWindow::event(QEvent*) () at /lib/x86_64-linux-gnu/libQt5Widgets.so.5
