            Bug ID: 454290
           Summary: Dolphin sometimes crashes when I close the window or
                    one of the tabs
           Product: dolphin
           Version: 22.04.1
          Platform: Neon Packages
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: dolphin-bugs-null at kde.org
          Reporter: yusufjamal1372 at gmail.com
                CC: kfm-devel at kde.org
  Target Milestone: ---

Application: dolphin (22.04.1)

Qt Version: 5.15.4
Frameworks Version: 5.94.0
Operating System: Linux 5.13.0-44-generic x86_64
Windowing System: X11
Distribution: KDE neon User - 5.24
DrKonqi: 5.24.5 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
It is highly unreliable but happens more often than not. dolphin crashes when I
close its window. Crashing upon closing the tab is less common  so I am not too
sure whether the two problems are related but closing the window almost 60% of
the time causes a crash.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
