Description Rainer Dorsch 2019-04-30 14:33:41 UTC 
Application: kmail (5.9.3)

Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 4.19.0-4-amd64 x86_64
Distribution: Debian GNU/Linux buster/sid

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

- Kmail did not display messages anymore, i.e. I assume akonadi already had a problem...

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
