            Bug ID: 443958
           Summary: Kmail crash/segmentation fault when quitting the
                    application
           Product: kmail2
           Version: unspecified
          Platform: Compiled Sources
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: telans at posteo.de
  Target Milestone: ---

Application: kmail (5.18.2 (21.08.2))
 (Compiled from sources)
Qt Version: 5.15.2
Frameworks Version: 5.87.0
Operating System: Linux 5.14.12-gentoo-dist x86_64
Windowing System: X11
Distribution: Gentoo Linux
DrKonqi: 5.23.0 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:

Quitting the application. Either through the task bar or through the GUI
interface.
I believe this bug has only just started with the introduction of the 5.23.0
packages, but I am not sure.

Hopefully the backtrace is useful (qtwebengine -g build times are a nightmare)

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
