You probably installed the Gnome3 ppa at some point. I had to run "sudo ppa-purge ppa:gnome3-team/gnome3" twice to revert nautilus back to a functional state.
You will loose any gnome3 packages you were running like gnome-shell. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to nautilus in ubuntu. https://bugs.launchpad.net/bugs/735727 Title: Nautilus gets stuck in infinite loop on startup -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
