You get AttributeError: 'NoneType' object has no attribute 'traverse'

see #220 for a case where this has tripped someone up. I just got tripped up on this...

We should have better error messaging for this case.

@rmarren1 you are on better Dev support program right? Are you interested in assigning this one and tackling it at some point? Should be relatively simple fix for decent gain!
