[Rivet] problems running rivet

Tevatron is a ppbar collider. It's main center-of-mass energies are 630,
1800 and 1960 GeV.

LHC is a pp collider. It's main center-of-mass energies are 900, 2360
and 7000 GeV.

Analyses depend on the initial state particles and the energy. They
might not book any histogram if you try to run them at the wrong
collider. Filling a non-existing histogram writes to non-allocated
memory, typically producing a segmentation fault. Therefore running the
same MC events through a CDF and an ATLAS analysis is usually not a
clever thing to do.

Please report if Rivet still segfaults when running with the proper
settings.

Cheers,
