            Bug ID: 439892
           Summary: Apparently random segmentation fault
           Product: konversation
           Version: 1.8.21041
          Platform: Fedora RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konversation-devel at kde.org
          Reporter: ben at goodger.nl
  Target Milestone: ---

Application: konversation (1.8.21041)

Qt Version: 5.15.2
Frameworks Version: 5.83.0
Operating System: Linux 5.12.12-xm1cacule.0.fc34.x86_64 x86_64
Windowing System: X11
Drkonqi Version: 5.22.3
Distribution: "Fedora release 34 (Thirty Four)"

-- Information about the crash:
- What I was doing when the application crashed:
Scrolling upwards in the liberachat #fedora-kde channel. But this happens at
seemingly random intervals whenever Konversation is open.
The same has happened in both Arch and Fedora since updating to kf5 5.83.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Konversation (konversation), signal: Segmentation fault
