There are some strange directories appearing in /home (so far, maybe in other locations too).These directories do not show up in ls but do with bash's tab autocomplete, when doing things like cd.The exact name of this mystery directory is .directory.ls and cd fail on these directories.P.S. There was more than one in /media, but they seem to have disappeared now.UPDATE: Output of ls -la /home:total 12drwxr-xr-x  3 root      root      4096 Jan  3 11:28 .drwxr-xr-x 23 root      root      4096 Jan  3 11:32 ..drwxr-xr-x 25 bharadwaj bharadwaj 4096 Jan  8 22:58 bharadwajlrwxrwxrwx  1 root      root        44 Jan  3 11:13 .directory -> /etc/kubuntu-default-settings/directory-home

They should be files not directories. They are created by the dolphin file browser in order to support per directory behavior of the file browser.See Here
