Nautilus goes into 'Sleeping' state and needs to be manually restarted before used again

[Wise Melon]

I have recently found that after upgrading to GNOME 3.20 on Ubuntu GNOME 16.04 that Nautilus randomly will suddenly go into the state 'Sleeping' and then although all applications will be able to be clicked off when clicking on the desktop, no other interactions with the desktop will be able to occur, for instance I am unable to select or drag anything on the desktop nor can I access the right-click menu nor open any icons. If I then go into the Activities Overview and attempt to open Nautilus nothing happens, in fact the only way seemingly to solve this problem is to manually end the Nautilus process and then restart it again in the normal way, after doing this all works fine until it decides to have nap again.

This has happened at least 3 times so far, 2 twice in the same session.
