Please remove the default mount option umask=0077 for udf-filesystems. Rationale: An udf-formatted usb-stick is great for exchanging data between Windows, Mac and Linux. It can be read on all systems and, unlike vfat, file permissions are preserved. Possible duplicate / workaround is described in bug 69145 (put default mount options into a config file).
Makes sense. Changed in http://cgit.freedesktop.org/udisks/commit/?id=6102a739f
