            Bug ID: 474477
           Summary: Crash when switching mails while PGP verification is
                    still in progress
    Classification: Applications
           Product: kontact
           Version: unspecified
          Platform: openSUSE
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: aheinecke at gnupg.org
  Target Milestone: ---

Application: kontact (5.24.0 (23.08.0))

Qt Version: 5.15.10
Frameworks Version: 5.109.0
Operating System: Linux 6.4.12-1-default x86_64
Windowing System: Wayland
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.27.7 [KCrashBackend]

-- Information about the crash:
When I view a signed Mail and the verification is not finished, because I have
a large keyring it usually takes a while for the first Mail. This behavior is
completely similar to
https://invent.kde.org/pim/messagelib/-/merge_requests/100 but now with 23.08

The crash can be reproduced every time.

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