Are you sure you have added all the model components, such as the string
decay code?   Your physics list should have the following lines:

  G4TheoFSGenerator* highEGammaModel = new G4TheoFSGenerator();
  G4GeneratorPrecompoundInterface* preComModel =
                         new G4GeneratorPrecompoundInterface();
  highEGammaModel->SetTransport(preComModel);
 
  G4QGSModel<G4GammaParticipants>* theStringModel =
                         new G4QGSModel<G4GammaParticipants>;
  G4QGSMFragmentation* fragModel = new G4QGSMFragmentation();
  G4ExcitedStringDecay* stringDecay =
                            new G4ExcitedStringDecay(fragModel);
  theStringModel->SetFragmentationModel(stringDecay);
 
  highEGammaModel->SetHighEnergyGenerator(theStringModel);
  highEGammaModel->SetMinEnergy(3.*GeV);
  highEGammaModel->SetMaxEnergy(100.*TeV);
