Created attachment 174933 [details] The Trash Bin ins't a big fan of drag and drop, it seems. Please notice how even the system got fooled, causing the file to rename itself into "(2)".
Can confirm. The trash bin seems to have a general problem of not auto-refreshing. If you trash a file from the command line (with the "trash-cli" package), the trash view won't update until manually pressing "F5".
This also happen when cut-pasting a file from the trash/bin. The trash/bin items list and the icon are not updated, and the file is still visible. Pressing F5 to refresh updates the list and icon, and the file is no longer in the list.
