types and other properties assigned in 

G4GDMLReadSolids.cc


it looks like there are quite a few mismatches compared to the enums defined in: G4SurfaceProperty.hh and G4OpticalSurface.hh


an example is:
  else if((stype == "dielectric_dichroic") || (stype == "3"))
  {
    type = dielectric_dichroic;
  }

which is incorrect since in 
source/materials/include/G4SurfaceProperty.hh


enum G4SurfaceType
{
  dielectric_metal,       // dielectric-metal interface
  dielectric_dielectric,  // dielectric-dielectric interface
  dielectric_LUT,         // dielectric-Look-Up-Table interface
  dielectric_LUTDAVIS,    // dielectric-Look-Up-Table DAVIS interface
  dielectric_dichroic,    // dichroic filter interface
  firsov,                 // for Firsov Process
  x_ray                   // for x-ray mirror process
};


"3" corresponds to dielectric_LUTDAVIS not  dielectric_dichroic. 

This mismatch will cause jobs to crash when the file defining dichroic properties can not be found.
