Description Christoph Thielecke 2018-05-18 18:22:30 UTC 
Application: kmail (5.7.3)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-20-generic x86_64
Distribution: Ubuntu 18.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I sent a mail and got notification it was sent. After some minutes I noticed in tree at outbox that it shows 1 new message in it. I went there but the folder is empty. The number of unread messages in this folder (1) still remains. After this I decided to quit kmail and then it crashed.

- Unusual behavior I noticed:

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