Oops, that doesn't work actually. When you try heuristic dissectors, the 
protocol name is added only when the dissector matches the packet. But 
if a /wrong/ heuristic dissector calls call_dissector_work() or a 
successful heuristic dissector, this subcall will make a wrong protocol 
to be added to the string. I don't see any simple fix :( Or maybe saving 
the current protocol string before calling heuristic dissectors, 
malloc'ing a new one, and finally appending only the right one. I'll try 
this.
