[rdiff-backup-users] problem with exlude/include on root (::/) target

[didldum]

i'm having troubles using the include exclude option when backuping up the / directory of a remote server. the same operation with a non-root target (like ::/etc) works fine.

simplified example:
rdiff-backup --include /etc/httpd  --exclude / 
myserver.com::/ root
-> backups nothing but an empty /etc directory, although /etc/httpd contains files.

what i am really trying to do:
rdiff-backup --include /vservers/default --exclude /vservers --exclude=/dev 
myserver.com::/ root
-> does not backup /vservers at all

i'm using v1.0.4 - any ideas?

thanks!
