            Bug ID: 463667
           Summary: Error message about file not existing when trying to
                    copy after unmounting
    Classification: Applications
           Product: dolphin
           Version: 22.08.3

SUMMARY
I have copied some files from a USB hard disk to an NFS mount; each had its own
tab inside the same Dolphin window. I then unmounted and disconnected the disk,
but kept the window open. I then tried to move some files from an SD card to
the same NFS mount, but Dolphin only gave me the option to copy files (not move
them). When I tried that, it complained that one of the files I copied earlier
from the USB disk didn't exist (as it was looking for it in the directory where
the disk was mounted) and prevented me from doing anything at all. Refreshing
the view didn't work, just like going back and forth between folders, and the
only thing that actually worked was to close Dolphin and open a new window.


STEPS TO REPRODUCE
1. Open a USB drive and a position outside of it (e.g. a remote folder) in the
same Dolphin window using tabs
2. Copy some files from the USB drive to the other position
3. Unmount and remove the drive, but keep the window open
4. Try to copy or move files to the remote folder

OBSERVED RESULT
The copy process doesn't start and Dolphin complains about the files on the USB
drive not existing.

EXPECTED RESULT
The copy process is performed as expected.
