I'm experiencing the weirdest problem right now. Nautilus is essentially not working right now. My desktop is frozen, clicking and right clicking doesn't work, I can't open anything in nautilus, etc. It simply is broken. The problem is that I can't exactly kill it with anything.

while true; sudo killall -9 nautilus ; done doesn't kill it.

I can't log out because I'm right in the middle of a long upload and I'm not going to kill it if I can help it. Is there something I can do to reload nautilus without logging out?

FYI, I was having the same issue. In my case, it appears to be caused by a faulty mount point somewhere in my FS tree.

Specifically, the culprit was a samba mount (cifs) that failed due to me losing VPN. As nautilus mentions these under 'Network' in the left sidebar, I'm guessing this caused it to hang. As a work-around I remounted all my volumes (sudo mount -a) and now nautilus is responsive again.

Have you tried nautilus -q already?

It exits (and restarts) nautilus. I use it when it hangs or when i need to "refresh" it after installing new nautilus context actions

Command hangs and nothing happens. Whatever's messed up here, it is seriously messed up. – Naftuli Tzvi Kay Aug 31 '11 at 18:04
Still same here in Ubuntu 12.04. Nautilus hangs quite often and kill/killall does not show any effect. 'nautilus -q' just states "Could not register the application: Timeout was reached". – Seven Apr 10 '13 at 12:44
12.10 and I get the same message "Could not register the application: Timeout was reached." – jwigley May 26 '13 at 23:44
Same here, with Ubuntu 14. – Bzazz Dec 4 '14 at 15:50
