            Bug ID: 480060
           Summary: KDE randomly restarted when launching Audacity
    Classification: Frameworks and Libraries
           Product: Akonadi
           Version: 5.19.3
          Platform: Ubuntu
                OS: Linux
            Status: REPORTED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org

                CC: carl at carlschwan.eu
  Target Milestone: ---

Application: akonadi_sendlater_agent (5.19.3 (21.12.3))

Qt Version: 5.15.3
Frameworks Version: 5.92.0
Operating System: Linux 6.5.0-14-generic x86_64
Windowing System: Wayland
Distribution: Ubuntu 22.04.3 LTS
DrKonqi: 5.24.5 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:   
I tried opening Audacity while sharing my screen in a Skype call in Firefox
Developer Edition 122.0b9, with the intent to show my father via Skype how he
can record audio in Audacity.   

- Unusual behavior I noticed:   
Suddenly both screens went black, after a few seconds showed some
`^@^@^@^@^@^@^@^@` in the TTY and KDE started back up with tons of "KDE:s
kraschhanterare" windows with different processes whose name begins with
"akonadi_", with the details stating it crashed with signal "Aborted (6)". 
Some of them include:   
* akonadi_mailmerge_agent   
* akonadi_unifiedmailbox_agent   
* akonadi_akonotes_resource   
* akonadi_maildir_resource   
* akonadi_archivemail_agent   
* [etc]   
Interestingly, KDE didn't crash again when opening and using Audacity in the
exact same situation again.   
Firefox does no longer have camera access since the crash, but I haven't
rebooted yet so that may fix the camera access.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
