Ok, mounts are something special. Maybe its the same as with nfs mounts.
Through nfs user root is matched as user nobody and has no special
rights on network filesystems. Thats normal. Backups can exclude mounted
filesystems. But the .gvfs directory is a normal directory in the local
filesystem, and root has no access to it. Thats not normal.
