Error message on filemove

SUMMARY
In some cases (see below) it is not possible to copy a file from one dolphin
window to another one.

STEPS TO REPRODUCE
1. Open Dolphin and navigate to the folder you want to place your files into
("target window")
2. Plug in a USB drive with the file on it.
3. Use the popup in the bottom right corner to mount and open the drive
("source window")
4. The drive will open in a new window
5. Drag a file from the source window to the target window

OBSERVED RESULT
File is not copied or moved. A red warning is displayed (see attached file).

EXPECTED RESULT
File is moved between the windows.

ADDITIONAL INFORMATION
It looks like Dolphin tries to perform the last action in the target window.
This can of course not be done when the file is eg. already deleted.
When I try to grab a different file, the file name in the error message of the
target window does not even change. So I (with of course no idea how it really
works) have the impression, that the source window hands over an action to the
target window, but does not specify the document name or the directory
correctly. So the target window tries to perform an action that can only be
incorrect.
