I just checked in a partial fix. Now the packets in your trace are indeed decoded, however, there are still some problems with the dissection, so I will leave the bug open until that is fixed too.
I looked at the src for that dissector, and I found that the enumerations for the bit mask for the flags field were all 'off-by-one' and that the endian-ess macro was there and used in numerous places. By shifting the mask enumerations, I got the dissector to work, but I didn't check the details. Fulko
