(I post here the same comment I posted for duplicate bug #1716277):
Same issue on my Ubuntu 17.10 beta, freshly installed (no upgrade).
Just for completeness, this behaviour happens by just dragging any file
from desktop to any other window of nautilus.
Dragging from nautilus to desktop works.

I confirm the wrong behavior described: nautilus hangs during the
transfer of MANY files via FTP, maybe exactly each time at the same
point for each transfer:
First test (copy of .thunderbird folder via ftp): it hanged after few
hundred bytes at each attempt, both via wireless and cable ethernet.
