no relationship of type ... in collection error

Hi, I was trying python-docx with a .docx file which I got from a .doc file ‘Saved as’ a Strict Open XML Document with Microsoft Office Standard 2013. Unfortunately, when I’m trying to open the .docx file with python-docx, I get the error below. Does anybody have any idea what the problem is ?

Traceback (most recent call last):
  File "fillin_subrep_contract.py", line 39, in <module>
    fillin_contract_docx(sys.argv[1])

    document = Document(wordfile)

Thanks @scanny, my bad for using a ‘Strict Open XML Document’. Re-generated my input document as a standard ‘Word document’ .docx and that seems to have fixed the problem.
