lrwxrwxrwx 1 stockrt stockrt 21 2009-01-29 23:00 stockrt/Roger/etc/namedb -> /var/named/etc/namedb
}}}

This destination does not exists in my local filesystem: /var/named/etc/namedb but I have this (broken) link in my local ""to backup"" directory: stockrt/Roger/etc

I think Tahoe should warn it but do not break just because of it.

The same should occur for read/access permission denied for files and directories.
