:param: without accompanying :type: results in "AttributeError: 'NoneType' object has no attribute 'startswith'"

The following script will produce an error:

#!/usr/bin/env python

from contracts import contract

@contract
def foo(bar, baz):
    '''
        :param bar: A thing.
        :type bar: str
        :param baz: Another thing.
    '''
    print bar, baz

if __name__ == '__main__':
    foo('hello', 'world')

The traceback is:

Traceback (most recent call last):
  File "foo.py", line 5, in <module>
    @contract
  File "/Users/geordan/src/contracts/src/contracts/main.py", line 166, in contract_decorator
