It appears that DeviceKit-disks, which is called by Nautilus to do the mounting, mounts NTFS (FUSE?) partitions with the 'default_permssions' option, limiting the permissions to the mounting user (and root). This breaks Samba sharing because of a lack of permissions on the (Windows) client.
I'm reporting this issue upstream, thank you for your feedback!
