Application: kmail (5.11.3)

Qt Version: 5.13.0
Frameworks Version: 5.59.0
Operating System: Linux 5.2.1-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed: Right click on a file in Dolphin, share, send by email

- Unusual behavior I noticed: The problem only appear when KMail is closed, the same operation works fine if KMail is already opened.

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
