           Summary: KMail crashes after restart after akonadi-restart when
                    mail was not being sent
    Classification: Applications
           Product: kmail2
           Version: unspecified

          Assignee: kdepim-bugs@kde.org
          Reporter: bugs.kde....@e3q.eu
  Target Milestone: ---

Application: kmail (5.21.3 (22.08.3))
 (Compiled from sources)
Qt Version: 5.15.8
Frameworks Version: 5.102.0
Operating System: Linux 6.1.12-gentoo-c x86_64
Windowing System: X11
Distribution: "Gentoo Linux"
DrKonqi: 5.26.5 [KCrashBackend]

-- Information about the crash:
I tried to send a mail using KMail, but it did not do that. So I restarted
akonadi (the go-to solution for most issues…). Then KMail's folder list became
empty. So I quit it and restarted. Then KMail crashed.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: KMail (kmail), signal: Aborted
