Comment 20 for bug 150471

Yes, it is still a bug. The login/logout is not the only case that is affected by this problem - when I am logged in as myself and I run a nautilus window as root, it does not exit normally. I have to kill the process manually after closing the nautilus window.

I don't know anything about the way Nautilus is coded, but the 2 cases where this problem occurs suggest to me that nautilus expects some service to be running as it is exiting, and if that service isn't running - the process hangs and eats up all the CPU.
