            Bug ID: 467489
           Summary: Konsole crash when searching on a loaded console
    Classification: Applications
           Product: konsole
           Version: 22.12.3
          Platform: Fedora RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: kdebz at electrozaur.com
  Target Milestone: ---

Application: konsole (22.12.3)

Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: Linux 6.1.15-200.fc37.x86_64 x86_64
Windowing System: X11
Distribution: Fedora Linux 37 (KDE Plasma)
DrKonqi: 5.27.2 [KCrashBackend]

-- Information about the crash:
- The Konsole had several 1000's lines of prints
- I was searching the Konsole for stings several times.
- The Default setting, and also here, was INFINITE history
.
Happens every time, on a loaded Konsole with a long history, while searching
(Always when the search wraps from end-to-start, or start-to-end)
.
On my previous KDE version I used to do even heavier searches, and it never
crashed.
Also on PREV KDE version (I used), search in Konsole was noticeably  faster

Thank you

The crash can be reproduced every time.

-- Backtrace:
Application: Konsole (konsole), signal: Aborted
