Bug 435916

Application: kmail (5.15.3 (20.08.3))

Qt Version: 5.15.2
Frameworks Version: 5.79.0
Operating System: Linux 5.11.15-lqx1.0.fc33 x86_64
Windowing system: X11
Distribution: Fedora 33 (KDE Plasma)

-- Information about the crash:
- What I was doing when the application crashed:
Restarting Kmail

- Unusual behavior I noticed:
Before closing Kmail, mail was taking a long time to sync. After quitting and starting the app twice it started and immediately crashed.

-- Backtrace:
