Hmmm... I think interpolation should be switched off by default in 
configspec reading -  but that would be a backwards incompatible change. 
Here is a workaround:

 >>> config = ConfigObj(configFile, configspec=ConfigObj(_configspec, 
interpolation=False, _inspec=True, list_values=False))
 >>> results = config.validate(validator)

All the best,
