What about doing something like this (taken from the packet-cops.c) ?

      proto_item *ti;
      ti = proto_tree_add_text(tree, tvb, offset, len,
                                            "PEP Id is not a NULL
terminated ASCII string");
      expert_add_info_format(pinfo, ti, PI_MALFORMED, PI_NOTE,
                                           "PEP Id is not a NULL
terminated ASCII string");

This highlights the section of packet data where the problem lies, but
displays a string not taken from the packet data.  It also adds an
expert item, which makes the item easier to navigate to.

Hope this helps,
Martin
