[Rivet] Rivet with asymmetric beams

[Eike von Seggern]

Hi Andy et al.,

following up on a thread a few days ago. I set up a directory on
hepforge with an example data file. The problem is that with the
PDG_HADRON_MULTIPLICITIES analysis 23 events of 10000 are processed. The
problem is (afaik) that the _io->fill_next_event(_evt.get()) call in
Run::readEvent() fails. So I'm not sure if it's a HepMC problem or a
rivet bug.

Thanks for your help.
Best
