Description Freek 2017-06-09 21:06:26 UTC

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.

If this is reproducible, could you add the backtrace from the "Developer Information" tab?

Backtrace from developer information tab

It is reproducible on every shutdown. I have attached the information.

Highest regards,

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?
