Just guessing:

Have you tried replacing the lines

        <match key="@storage.originating_device:usb.vendor_id" int="0x177f">
          <match key="@storage.originating_device:usb.product_id" int_outof="0x0460">

with

      <match key="usb.vendor_id" int="0x177f">
        <match key="usb.product_id" int="0x0460">

in 20-libmtp9.fdi
I see a different syntax on that file on my Ubuntu 10.4 system
