Bug ID: 459330
Summary: KMail crashes after showing and closing the e-mail
source code and closing the message window.
Classification: Unclassified
Product: kmail2
Version: unspecified
Platform: Debian stable
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kdepim-b...@kde.org
Reporter: sergej....@googlemail.com
Target Milestone: ---
Application: kmail (5.15.3 (20.08.3))

Operating System: Linux 5.10.0-18-amd64 x86_64
Windowing system: X11
Distribution: Debian GNU/Linux 11 (bullseye)
-- Information about the crash:
- What I was doing when the application crashed:
Following scenario:
- Starting KMail normally
- Wondering, why I can switch between the e-mails, but get no e-mails displayed
on the main window since today.
- Double-click some message and open the message window.
- Wondering, why I cannot see the e-mail on the message window as well. Just a
white area.
- Hitting the "V"-key to get the e-mail code displayed. Success.
- Closing the e-mail code window.
- Closing the message window.
= crash!
It is reproducible.
- Unusual behavior I noticed:
If I start KMail over CLI it gets filled with this error:
org.kde.pim.webengineviewer: WebEngine render process crashed
The crash can be reproduced every time.
-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
