Bug 447115

SUMMARY
When attempting to move a file /mnt/ext4/Test.txt from an ext4 partition to a ntfs partition /mnt/ntfs, dolphin reports an "Access denied to /mnt/ntfs/Test.txt." error with the option to retry or cancel. When canceling, one can see that the file was indeed moved. When doing this in split view, the view of the old location will however still show the old file until one refreshes. When retrying, this gives the error "The file or folder does not exist." and one has to press "Cancel" as "Retry" would continue showing this dialog. (This last dialog does technically make sense as the file was indeed moved.) Note that the software does not crash in any case. (This did happen with earlier versions but is already fixed, see #364039 and #368287.)

The error does not appear when moving a file from a ntfs partition to an ext4 partition.

The error does not appear when copying the file (both from ext4 to ntfs *and* vice versa).

The partitions are mounted as follows:
UUID=EXT4PART /mnt/ext4 ext4    noatime,acl,user_xattr,nofail 0 2
UUID=NTFSPART /mnt/ntfs ntfs-3g noatime,users,gid=users,fmask=113,dmask=002,locale=en_US.UTF-8 0 0



STEPS TO REPRODUCE
1. Move a file from an ext4 partition to a ntfs partition using dolphin 20.04.2

OBSERVED RESULT
The file is moved but an access-denied error message appears and the view of the source location is still showing the old file. (I have no indication as to what actually went wrong.)

EXPECTED RESULT
The file is moved, no error message appears.

ADDITIONAL INFORMATION
I am using an SSD, which should explain why I am using the noatime mount option.
