Sorry - I wasn't saying the device was truncating it. I was saying the
libmtp code is reading the ObjectSize property and then truncating it
if it's a 64bit value in certain situations. I don't understand why it
does that, but at the end of the day there's a code path that works
which is the one that gets used in the right places.
