Bug#741631: nautilus can take 100% CPU even if no nautilus window is running

[dAgeCKo]

Package: nautilus
Version: 3.8.2-2
Severity: important
Debian: Testing amd64
Regression: No
gnome-shell: 3.8.4-5+b1
gnome-session: 3.8.4-3

Sometimes (again !) nautilus can takes up to 100% CPU usage even if no 
nautilus window is currently running.
This is really annoying and weird.
Killing the process actually makes the things turn good.
