unpack_smb_acl unknown error

[Alain Content]

Hi,

Since upgrading to Snow Leopard, my backup script throws an error msg :

rsync: unpack_smb_acl: sys_acl_get_info(): Unknown error: 0 (0)

This happened both with 3.0.5 and 3.0.6 that I just installed.
Can someone tell me what it means ? I have no clue on what/where to  
look for.

Thanks
