The test failure appears unrelated to this pull request. The test failed to find file:ttbarForMetTests.root. That file was generated by the same script. From the log output it looks like the generate step failed with a pythia error:

 PYTHIA Error in Pythia::check: charge not conserved  
 PYTHIA Abort from Pythia::forceHadronLevel: check of event revealed problems  
 PYTHIA Error in Pythia::check: unmatched particle energy/momentum/mass  
 PYTHIA Warning in Pythia::check: not quite matched particle energy/momentum/mass
