If I try to launch Nautilus in whatever way (from Unity, Terminal), it doesn't launch. Terminal gives me these outputs:
launch
name@machine:~$ nautilus

Trasovací/ladící past (SIGTRAP) (core dumped [obraz paměti uložen])
launch with sudo

I tried to reinstall Nautilus (with purge), reboot, remove ~/.config/nautilus, step by step at first and then all at once but nothing worked. I haven't changed any configuration or made any significant changes in Ubuntu system since installation. Yesterday Nautilus worked, today doesn't. Does anybody know how to fix it?
