[New-bugs-announce] [issue29851] importlib.reload references None object

[Richard Cooper]

New submission from Richard Cooper:

importlib.reload doesn't work; gives an error about NoneType having no name attribute.

See attached a simple repo testcase

When run it yields the following [disappointing] result.  I'm running Python3.0.6.1 (installed from brew) on OSX 10.12.3

```
iMac:python_package_loader cooper$ python3 bug.py 
module loaded
Traceback (most recent call last):
  File "bug.py", line 14, in <module>
    importlib.reload(sys.modules[moduleName])
  File "/usr/local/Cellar/python3/3.6.0_1/Frameworks/Python.framework/Versions/3.6/lib/python3.6/importlib/__init__.py", line 166, in reload
    _bootstrap._exec(spec, module)
  File "<frozen importlib._bootstrap>", line 589, in _exec
AttributeError: 'NoneType' object has no attribute 'name'
```
