I have recently found out that when cd is inserted not only Thunar but also nautilus starts. I don't use nautilus, so I tried to remove it and found a very strange thing
zsh: correct 'nautilus' to '_nautilus' [nyae]? y
_arguments:comparguments:312: can only be called from completion function
% which nautilus
/usr/bin/which: no nautilus in (/usr/local/bin:/usr/bin:/bin:/home/obschij/bin:/usr/local/sbin:/usr/sbin:/sbin)
% rpm -qa | grep -i nau
% ps -ax | grep -i nau
Warning: bad syntax, perhaps a bogus '-'? See /usr/share/doc/procps-3.2.8/FAQ
13238 ? Sl 0:24 nautilus --no-desktop file:///home/obschij/Download
While it seems that there is no nautilus in the system but it is somewhere there...
Any help on what's going on would be helpful.
