please use bluez-libs-3.1 and bluez-utils-3.1 and make sure that the
sdpd from this release is running and you use its sdptool. After that
issues the following commands:

# sdptool add sp

# sdptool browse local

        Attribute 0x0101
                String COM Po

You will see that attributes 0x100 and 0x101 are not matching.
