            Bug ID: 480595
           Summary: Dolphin sometimes crashes when moving files to another

    Classification: Applications
           Product: dolphin
           Version: 23.08.4

  Target Milestone: ---

Application: dolphin (23.08.4)

Qt Version: 5.15.12
Frameworks Version: 5.114.0
Operating System: Linux 6.7.2-arch1-1 x86_64
Windowing System: Wayland
Distribution: Arch Linux
DrKonqi: 5.27.10 [KCrashBackend]

-- Information about the crash:
This has only happened once so far, but this is related to another bug in where
copy and pasting files to another directory causes Dolphin file manager to
crash.

Upon looking at the crash log, this is a Segmentation fault exception. Perhaps
there's a memcpy or malloc function in there that's copying memory to the wrong
location?

And if the exception is identical to the related bug, then it's likely the same
bug.

This seems to happen only when moving multiple files and folders at a time,
into another directory.

The reporter is unsure if this crash is reproducible.

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