            Bug ID: 432309
           Summary: Copying and pasting folders crashed (maybe because of
                    broken symlinks)
           Product: dolphin
           Version: 20.12.1
          Platform: Fedora RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: dolphin-bugs-null at kde.org
          Reporter: seplexfake at tutanota.com
                CC: kfm-devel at kde.org
  Target Milestone: ---

Application: dolphin (20.12.1)

Qt Version: 5.15.2
Frameworks Version: 5.78.0
Operating System: Linux 5.10.10-200.fc33.x86_64 x86_64
Windowing system: Wayland
Distribution: Fedora 33 (Thirty Three)

-- Information about the crash:
- What I was doing when the application crashed:

I was modifying an icon theme. One of the themes had a folder symlink called
'devices' that linked to '../icon-theme/devices. The example name of that theme
was 'icon-theme-dark'
To be more specific in the 22x22 folder.
In that folder there was a symlink called 'animations' that linked to
'../icon-theme/22x22/animations'
And another aclled apps one linking to '../icon-theme/22x22/apps'

and more folders and symlinks...

I copied all the folders and symlinks to a directory that already has the
folder names, but not symlinks, I wrote into the folders and overwrote
everything.

After that I get a window saying 'could not delete file
/home/username/icon-theme/animations.' And I can either retry, skip, skip all
and cancel. Retry doesn't crash, but the same windows pops up again. Skipping
all doesn't crash and cancelling doesn't crash.

After I skip once I get a window saying 'could not delete file
/home/username/icon-theme/apps.' Clicking on skip makes dolphin crash.

Tried this again and results in the same behaviour

I have also crafted a directory which is designed to simulate the actual crash,
but I don't really know why it causes to crash. I will upload that to github,
see the comments for the link, since I have not uploaded it at the time of
writing this.

This is the backtrace of that:
