Application: akonadi_maildispatcher_agent (5.12.0)

Qt Version: 5.12.3
Frameworks Version: 5.61.0
Operating System: Linux 4.15.0-58-lowlatency x86_64
Distribution: KDE neon User Edition 5.16

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

Trying to send an email. I added two-factor authentication and XOAUTH stopped working so I made an app password for kmail which worked for a while but seems to be broken now. I try to send the email, a dialog pops up asking for a password, I supply a password and then it crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: akonadi_maildispatcher_agent (akonadi_maildispatcher_agent), signal: Segmentation fault
