            Bug ID: 444916
           Summary: Kontact crash when quitting while using KMail with
                    open e-mail windows
           Product: kontact
           Version: unspecified
          Platform: Debian stable
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: lassi_surinen at yahoo.ca
  Target Milestone: ---

Application: kontact (5.15.3 (20.08.3))

Qt Version: 5.15.2
Frameworks Version: 5.78.0
Operating System: Linux 5.10.0-9-amd64 x86_64
Windowing system: X11
Distribution: Debian GNU/Linux 11 (bullseye)

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

1) While using Kontact, switch to KMail component and open any e-mail in a
separate window.

2) With the e-mail window still open, switch back to Kontact main window and
quit by any means (Ctrl+Q or other hotkey, close window by means of window
manager close button, etc). Note that KMail no longer needs to be the active
component in Kontact window, so long as an open e-mail window exists.

3) Kontact crashes.

The crash can be reproduced every time.

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