Description Volker 2019-08-02 08:09:21 UTC 
Application: kontact (5.9.3)

Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 4.19.0-5-amd64 x86_64
Distribution: Debian GNU/Linux 10 (buster)

-- Information about the crash:
I moved some mails to a (sub-)folder.
To check, i started the separate search window.
The search lists 10 mails from the given sender.
The fast search input within my folder gives me just 2 mails.
I exit kontact with ctrl+q => kontact segfaults.
After restart, all 10 mails are shown within the folder.

Greetings, Volker

The crash does not seem to be reproducible.

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

Comment 3 Volker 2022-09-25 12:16:20 UTC 
Hi,
as I wrote, the crash disappears after clearing the akonadi cash for the respective folder.
It is not occurred again.
I'm did some updates in between and use now kontact 5.21.0 (22.08.0).
I'm not sure about the state of this bug report, so I did not change.
Greetings, volker
