the toolbar has been changed.
splitting into groups is enabled.
columns changed.

dolphin (20.08.3) using Qt 5.15.2

- What I was doing when the application crashed:

I was copying a folder from local disk to to another folder in a smb:// share using split view. Merge dialog appeared after directory creation at the destination although there was no duplicate in the destination before copying and after chosing write into in the merge dialog dolphin crashed. 

I did several trials and result was always the same.

Comment 5 Taner 2020-12-18 14:14:35 UTC
I have just tested the same copy operation after mounting the network share using fstab. 
- When mounted as a NFS share there is no problem, copy opreation finished successfully.
- When mounted as a SMB share the same issue occured again and Dolphin crashed at the moment of checking "Apply To All" in the merge dialog.

I hope this helps.

Comment 7 Graham Powell 2020-12-18 17:29:33 UTC
I'm also experiencing this on 20.12.0. Dolphin crashes every single time I click "write into" when copying/pasting directories with files.
Comment 8 JSladek 2020-12-18 18:31:59 UTC
I am seeing the same thing on PCLinuxOS when I use Ark and the decompressed files overwrite files at the destination AND the option "apply to all" is check marked.  Until "apply to all" is marked, I can overwrite each item indivually as it is presented.

The same crash occurs with Dolphin when copying folders with subfolders and an overwrite is detected.

I have not had any system crashes occur with either event, but I do have "extraction failed" or "copy failed" notifications and in Konsole will get a "segmentation fault".

These events are reproduceable.
Comment 9 Dzen Pythom 2020-12-18 20:12:43 UTC
Confirmed bug
ArchLinux
Dolphin 20.12

also: Krusader have similar problem with moving (using one library?)

Comment 11 JSladek 2020-12-19 13:18:27 UTC
In addition to comment 8, once any folders have been copied one at a time, "apply to all" can be ticked and remaining individual files will copy without failure.  

This works in both Ark extraction and Dolphin folder copy.  The problem seems to only exist with an "apply to all" folder overwrite.

This makes the overwrite dialog unusable and is currently annoying my wife. raising priority to VHI. :)
Comment 15 Szymon Kosecki 2020-12-22 18:28:28 UTC
I am seeing the same behaviourwhen moving/copying files in Dolphin or Krusader. As soon as "Apply to all" is clicked, the app initiating the operation will crash. - Running on Arch linux and up to date.

RenameDialog: Add missing nullptr initialization

It fixes a crash when pressing `Apply to All` in those cases where
the action was not present, as the code checks for nullptr

I have the same problem, trying to overwrite files and folders, crashes as soon as I tick apply to all. 
I'm using OpenSuse tumbleweed, and its up to date.

New crash information added by DrKonqi

dolphin (20.12.0) using Qt 5.15.2

- What I was doing when the application crashed:

Copying several directories with Dolphin to another directory and select Apply to all, when asked to Write into the folder, crashes Dolphin. In my case, I was patching an application. I downloaded the patch and copied the new files over to the original destination. Since there have been several directories, I wanted to use Write into and Apply to all. Selecting Apply to all crashed Dolphin. I tried several time and it crashed always. 

Sometimes it seems, that if only two or three directories are selected, it works fine. Also, I had no issues, overwriting 300 files, selecting the Apply to All option. It seems to be related to directories only. 

- Custom settings of the application:

No need to add new comments; the bug is already fixed in Frameworks 5.78.

New crash information added by DrKonqi

dolphin (20.12.1) using Qt 5.15.2

- What I was doing when the application crashed:

Copying and moving files from a mounted drive caused Dolphin to crash 3/5 times. That fraction is an anecdote of my experience today. I updated to framework 5.78 today. I did not experience this bug in prior versions.
