tshark can be used to display fields using the -T option.
If the same field occurs a number of times within a protocol,
only one value ( the last ) gets displayed.

As far as I can see the error looks like it comes from the 
routine proto_tree_write_fields. 

The -T pdml option gives the correct output, but is too voluminous.

Can anyone help with a fix?
