I just gave it a quick try on a protocol registering to "udp.port".

The first problem occurred in an assert in splash_update, proposed
patch attached.

The fix adds 2 (one for protocol, one for handoff) but in reality you need to
add 2 for _each_ python plugin registered.  
 
I'm not sure how to fix things, but the real problem seems to be that the counts are
"hard coded" in proto_reg_count, and handoff_reg_count in epan/dissectors/register.c 
and don't take into account that the python ones are added dynamically.
 
On a related note...  Has the Python work been orphaned?  I can't find much in
the way of others testing/fixing these basic bugs.
