            Bug ID: 410510
           Summary: Segfault on quit
           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: volker.groll at web.de
  Target Milestone: ---

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
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
