After bumping to latest revision it seems that the earlier fixed "add ntfs-3g to known filesystems" got undone...
To "fix" that you can add ntfs-3g to /etc/filesystems http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/sys-fs/udisks/files/udisks-1.0.2-ntfs-3g.patch?view=markup We need this patch applied, or ship our releases with ntfs-3g added to /etc/filesystems (part of basesystem)
