I'm checking, whether the presumably read GenEvent contains 0 vertices.

Does this really have to do with HepMC 2.05? Doesn't 
IO_GenEvent::fill_next_event already return a bool about whether it 
succeeded or not? So it's just a matter of knowing how to read that in our 
Python interface, and I didn't know enough about this, thus the comment in 
SVN log.
