Hi Anton,

thanks for that bug report. It's kind of hard to blame Rivet in this
case, though. The AGILe installation is using an ancient HepMC version
(2.03.11) which doesn't have cross-section information support. If you
then run a Rivet analysis that requires the cross-section for
normalisation then anything can happen.

True, Rivet should throw an error, and I'll fix that. But you should
consider using a more recent version of HepMC like 2.06.
