I know this post is really old. But, I came across the same error recently and thought it would benefit others if I mentioned it here. I did not use GDML though.
In my application, I had to define an isotope. G4Isotope class takes these parameters.
G4Isotope(const G4String& name, //its name G4int z, //atomic number G4int n, //number of nucleons G4double a = 0.); //mass of mole
Third parameter should be number of nucleons (#protons + #neutrons). By mistake I entered only #neutrons there. So, I got this error message which is very similar to what ZachB has seen.
G4NucleiProperties::GetNuclearMass: Wrong values for A = 2 and Z = 3 G4NucleiProperties::GetNuclearMass: Wrong values for A = 2 and Z = 3 G4PDGCodeChecker::CheckPDGCode : ??? Illegal PDG encoding for nucleus PDG code=1000030020 Particle Li2 has a strange PDGEncoding

So, you have to be careful when you define isotopes.
