Your home folder most probably contains some special files/pipes for
which Twisted can not read the attributes.
When listing a folder, twisted FTP and SFTP servers are querying for
file attributes and they will return permission denied if one of the
file attributes can not be retrieved.
I am not sure if this is a bug or a feature.
