Application: kmail (5.10.3)

Qt Version: 5.12.0
Frameworks Version: 5.56.0
Operating System: Linux 4.15.0-46-generic x86_64
Distribution: KDE neon User Edition 5.15

-- Information about the crash:
- What I was doing when the application crashed:
KMail stopped displaying messages; Akonadi logged database timeout errors. When I quit KMail in this situation (which happens very often) with CTRL+Q, I get this crash report. I also wrote about this problem here: https://forum.kde.org/viewtopic.php?f=215&t=159963

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
