This directory it is actually a link to a directory in another filesystem:
lrwxrwxrwx 1 giov users 28 May 29 2002 web -> /usr/local/httpd/htdocs/giov
Of course in normal conditions I have permissions to browse this directory, which is owned by me.
But if I try to enter into this directory with winscp, the program locks up and I have to ctrl-alt-del to terminate it.
Looks like a bug...
