Several possibilities. First note that in G4OpWLS::PostStepDoIt() there are four places the method returns without setting a secondary.

You could try any of
1) Run in a debugger and put breakpoints at these lines (compile Geant4 in debug mode first)
2) Put G4cout statements before these lines, recompile Geant4, run with verbosity 0.
3) Note that you don't need all the output. Use the existing code. Note that with verbosity 2 the return on line 204 will print an message. Try to just print that. e.g.
$ ./MyExecutable macro.mac | grep "No WLS photon"

Presumably, but you would have to decide on whether this is physically realistic.
