            Bug ID: 474521
           Summary: Dolphin crashes when overwriting file
    Classification: Applications
           Product: dolphin
           Version: 23.08.0
          Platform: Archlinux
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: dolphin-bugs-null at kde.org
          Reporter: tuantran1632001 at gmail.com
                CC: kfm-devel at kde.org
  Target Milestone: ---

Application: dolphin (23.08.0)

Qt Version: 5.15.10
Frameworks Version: 5.110.0
Operating System: Linux 6.5.3-273-tkg-bore x86_64
Windowing System: X11
Distribution: EndeavourOS
DrKonqi: 5.27.8 [KCrashBackend]

-- Information about the crash:
Dolphin crashed when ever I attempted to overwrite a file, either by moving or
copying. Normal copying and moving without overwriting is fine, however.

Note: This is on EndeavourOS, which is Arch-based. I could not find the distro
in the "distribution method" so I chose the closest one.

The crash can be reproduced every time.

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