screenshot of htop when problem appers

Description of problem:

Sometime, without "really" using nautilus (copying amounts of files or so) or even without open/start nautilus, my laptop's fan raise speed and "htop" in gnome-shell shows that "/usr/bin/nautilus --no-default-window" is using one core at 99-100% with two processes.



Version-Release number of selected component (if applicable):

$ /usr/bin/nautilus --version
GNOME nautilus 3.8.2



How reproducible:
Sometime this happens directly after booting (without opening anything). Sometime it appears when I start some programs like Thunderbird, Pidgin or Chromium or at least nautilus itself ( -> "files" via Gnome).



Actual results:
One CPU-Core at 100% usage.

Expected results:
Nothing unusual.

Additional info:
I have to kill the process via its PID or restart the laptop.
