The plugin dissector will be called when a new capture has been started 
that has packets which belong to your plugin dissector.  When a new file 
is loaded, the same happens if there are packets belonging to your 
dissector.  A dissector is called once per packet for every packet 
belonging to it.  What are you trying to accomplish?
