Copied from numpy/numpy#421.
When documenting at the same time properties and normal attributes, nothing is rendered at all.
e.g. in the example below:
class ExampleClass1
    """
    Attributes
    ----------
    prop1
    attr2 : string 
        Some string attribute. 
    """
    @property 
    def prop1(self)
           """ Property 1 docsting """
           pass
The docstring is transformed in the following reST (docscrape_sphinx.py:57,strmember_list) :
.. rubric:: Attributes
.. autosummary::
   :toctree:
   prop1
==============  ================  ==========
        attr2             string  Some string attribute
==============  ================  ==========
but this is not correct as a newline is missing after "prop1":
