Question mark at the end of the sentence crashes DeterministicGenerator.py

[awesomebytes]

Given a grammar that has some question mark at the end of a sentence it crashes with:

Traceback (most recent call last):
  File "DeterministicGenerator.py", line 129, in <module>
    expansions = processRHS(rule.rhs)
  File "DeterministicGenerator.py", line 114, in processRHS
    return processSequence(rhs)
  File "DeterministicGenerator.py", line 68, in processSequence
    componentSets.append(processRHS(component))
  File "DeterministicGenerator.py", line 116, in processRHS
    return processDisjunction(rhs)
  File "DeterministicGenerator.py", line 90, in processDisjunction
    disjunctExpansions.extend(processRHS(disjunct))
  File "DeterministicGenerator.py", line 120, in processRHS
    return processNonTerminal(rhs)
  File "DeterministicGenerator.py", line 76, in processNonTerminal
    return processRHS(grammar.getRHS(nt))
  File "/home/sam/magiclab/sentences_generator/JSGFTools/JSGFGrammar.py", line 153, in getRHS
    raise ValueError("Rule not defined for " + str(nt))
ValueError: Rule not defined for <objq0>

A minimal example of crashing grammar:

#JSGF V1.0;

grammar crashtest;

<crashconcept> = will this crash?;

public <command> = <crashconcept>;  

And my bigger crashing grammar:

#JSGF V1.0;
