Note: Version is 5.5.2 but this is not an option in this bug tracking system. Kmail crashes just before shutdown. Since Kmail is usually in my notification area as an icon, I never shut it down before a system shutdown. When I do a system shutdown a Kmail error pops up saying Kmail crashed. Expected behaviour: Kmail exits nicely when shutting down my laptop.
Created attachment 106015 [details] Screenshot of last message before shutdown
If this is reproducible, could you add the backtrace from the "Developer Information" tab?
Created attachment 106069 [details] Backtrace from developer information tab It is reproducible on every shutdown. I have attached the information. Highest regards, Freek
According to bug 378315, this is a crash that appears in Qt >= 5.8.0, but not in Qt == 5.7.1. Which Qt version are you using?
