Takes about 100% of CPU even if no pcmanfm window is open in the UI

[Jarno Suni]

I had some pcmanfm windows open, but I closed them. Still:
$ ps aux | grep pcmanfm
jarno 1794 0.0 0.8 804920 17912 ? Sl 14:37 0:15 pcmanfm --desktop --profile lubuntu
jarno 2587 0.0 0.4 435528 10100 ? Rl 14:53 0:26 gksu pcmanfm /media/jarno
root 2590 0.0 0.0 84868 1432 ? Ss 14:53 0:00 /usr/bin/sudo -H -S -p GNOME_SUDO_PASS -u root -- pcmanfm /media/jarno
root 2593 73.2 1.2 757112 25652 ? Rl 14:53 378:39 pcmanfm /media/jarno

Process 2593 takes about all CPU power of a core.
