Followed the instructions but get this exception. I assume this is because the locales is not loaded properly, but either if it's me (I doubt that by the look of what is happening - locale is set to default "en") or it's a plugin issue this is the type of errors that should be catched with more proper exception that gives info about what could be incorrect.

You have a nil object when you didn't expect it!
The error occurred while evaluating nil.parameterize
