Nautilus "Open in Terminal" is performing some useless operations and causes an abnormal CPU activity on opening terminal

[Alexey]

When i select "Open in Terminal" from Nautilus menu, the terminal opens in the current folder (as expected) and the cursor rapidly blinks for a few seconds, ignoring attempts to type anything at the prompt. During this period, the whole system freezes a bit and the processor usage can reach 40% on a 6th generation Intel Core i7.

I am using Ubuntu GNOME 16.04.1.

nautilus:
  Installed: 1:3.18.4.is.3.14.3-0ubuntu5

Sometimes the processor usage reaches 60%, and i believe i hear the fan spinning up, because my computer is getting so hot opening a terminal!

I have noticed that this bug occurs if i select "Open in Terminal" from Nautilus window menu, but not if i use "Open in Terminal" from a pop-up contextual menu that shows on right-clicking in an empty space in a Nautilus window.

According to GNOME, GNOME 3.18 is not supported anymore:

Actually, the same abnormal CPU usage happens if i use other commands from Nautilus window bar menu, like "New Folder" or even "New Tab". I will make a new bug report with a more appropriate title and issue description.
