The "Open a New Window" selection in Nautilus stopped working today. I closed all my windows and when I tried to restart Nautilus by clicking on the folder icon, it flashed as if it was trying to start up and then just quit again. Does anyone know what caused this bug and how to fix it?
I think it because of nautilus corrupted. Just reinstall nautilus. press Ctrl + Alt + T then enter
sudo apt-get install --reinstall nautilus
Solved the problem. It was a memory issue. I closed some apps, then ran
nautilus -q and restarted it through the unity menu.
