           Product: kontact
           Version: unspecified
          Platform: Ubuntu Packages
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: eeickmeyer at ubuntu.com
  Target Milestone: ---

Application: kontact (5.20.3 (22.04.3))

Qt Version: 5.15.4
Frameworks Version: 5.96.0
Operating System: Linux 5.15.0-24-lowlatency x86_64
Windowing System: X11
Distribution: Ubuntu Kinetic Kudu (development branch)
DrKonqi: 5.25.4 [KCrashBackend]

-- Information about the crash:
Sometimes an email that has been filtered-out to another folder or otherwise
deleted from the inbox, it remains in the inbox. When this happens, selecting
it will cause the application to allow other emails to be selected, but the
application will hang and not display the email or open the email in a window.
Closing the application results in a crash.

The crash can be reproduced every time.

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