Adding new files to the source-folder during a move operation causes Dolphin to incorrectly draw items once the operation finished.

Reproducible: Always

Steps to Reproduce:
1. Select (e.g.) 5 items & press Ctrl+x to cut them for pasting.
2. Go to another folder and paste the items.
3. While the move operation is on-going, add new files to the source-folder (the one where you cut the items) outside of Dolphin.

Actual Results:  
After the move operation finished, the source folder shows 5 different items as being cut (always the same amount as you had selected for cutting before). The items don't actually seem to be in the clipboard, it's merely a visual glitch: the icons are transparently drawn as if they were cut right now.

Expected Results:  
The items shouldn't appear "cut".

I observed this in "Detail view mode". I'm not sure whether it's a problem specific to this view, though.
