Details:

Original host permissions:

$ sudo ls -la /usr/lib/ssl/private/
total 12
drwxr-x--- 2 root ssl-cert 4096 2009-10-16 08:09 .
drwxr-xr-x 4 root root     4096 2009-10-16 08:10 ..
-rw-r----- 1 root ssl-cert  887 2009-10-16 08:09 ssl-cert-snakeoil.key


Backed-up directory permissions:

$ sudo ls -la /backups/thehost/usr/lib/ssl/
total 24
drwx------  4 backup backup  4096 2009-10-16 16:38 .
drwx------ 40 backup backup 12288 2009-10-16 16:38 ..
lrwxrwxrwx  1 backup backup    14 2009-10-16 16:05 certs -> /etc/ssl/certs
drwxr-xr-x  2 backup backup  4096 2009-10-16 08:10 engines
drwxr-xr-x  2 backup backup    84 2009-10-16 08:10 misc
lrwxrwxrwx  1 backup backup    20 2009-10-16 16:05 openssl.cnf ->
/etc/ssl/openssl.cnf
lrwxrwxrwx  1 backup backup    16 2009-10-16 16:33 rdiff-backup.tmp.9770 ->
/etc/ssl/private


Notice that the source on the client (and the backed-up version) is
drwxr-x--- 2 backup backup

So user "backup" is given r-x (*not* rwx), and thus access fails. Once I make
/etc/ssl/private on the clinet drwxrwx--- it works.



The stack trace is:
