Description Tim Folger 2020-01-02 19:06:09 UTC 
Application: kontact (5.13.0 (19.12.0))

Qt Version: 5.13.1
Frameworks Version: 5.65.0
Operating System: Linux 5.3.12-2-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
I'm running kontact version 5.13.0, kde plasma 5.17.4, kde frameworks 5.65.0, Qt 5.13.1, kernel 5.3.12-2 on opensuse tumbleweed. After a recent upgrade kontact has been crashing whenever I switch from akregator to kmail.

The crash can be reproduced every time.
