            Bug ID: 431038
           Summary: Dolphin crashed when opening/closing tree folder
           Product: dolphin
           Version: 20.12.0
          Platform: openSUSE RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash

  Target Milestone: ---

Application: dolphin (20.12.0)

Qt Version: 5.15.2
Frameworks Version: 5.77.0
Operating System: Linux 5.10.1-1-default x86_64
Windowing system: X11
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
Operating System: openSUSE Tumbleweed 20201229
KDE Plasma Version: 5.20.4
KDE Frameworks Version: 5.77.0
Qt Version: 5.15.2
Kernel Version: 5.10.1-1-default
OS Type: 64-bit
Processors: 8 × Intel® Core™ i7-7700HQ CPU @ 2.80GHz
Memory: 15.5 GiB of RAM

- What I was doing when the application crashed:

When navigate the directory tree and expand or collapse a folder then Dolphin
crashes.
This usually happens when the directory has hundreds of files.
It also often happens that repeated files or subfolders are displayed.

The crash can be reproduced sometimes.

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