Bug 425842

Application: kontact (5.15.40 (20.11.80))

Qt Version: 5.15.0
Frameworks Version: 5.74.0
Operating System: Linux 5.8.0-1-default x86_64
Windowing system: X11
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
Kontact ran like normal.
In KMail, I pressed A to Reply to All and Kontact crashed.
Subsequent attempts to initiate Kontact crash immediately.
If I revert to a previous package version and then back, I can open it again, select Reply to All and the crash is reproducible.
Downgrading kpimtextedit and related packages seems to workaround the issue, so I believe this is the culprit.

- Custom settings of the application:
I have a simple template for Reply to All, I'll test it with default R to Reply when I have more time.
I am running Kontact from the master branch in openSUSE Krypton. With a simple command I may revert all Kontact-related packages back to openSUSE Tumbleweed.

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
