Today I encountered a strange bug:

I was copying a folder to an external usb drive. I launched this operation normally, via nautilus GUI opened using the launcher from gnome-shell as normal (the reason why I specify this, will be soon clear).

then I launched a nautilus instance via terminal using this command `nautilus .local` (I was in my home)

this command results in a new nautilus window launched but also a new little window (without name or title) containing the operation drop-down window that usually appears when clicking on the "pie" button beside the search, etc., on the right of the top bar of nautilus.

Then I closed the dwarf window and this results in the closure of all nautilus instances.

I'm on Arch Linux x86_64, gnome 3.20, nautilus  3.20.1+17+gf84d431-1, nautilus-sendto 3.8.4-1 and nautilus-renamer 4.0-1

the attached screenshot shows the problem
