[New-bugs-announce] [issue21720] "TypeError: Item in ``from list'' not a string" message

[David Szotten]

New submission from David Szotten:

```
>>> __import__('fabric.', fromlist=[u'api'])
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
```

accidentally ended up with something like this via some module that was using `unicode_literals`. stumped me for a second until i realised that my variable was a string, but not `str`. would be nice with a custom error message if this is a unicode string, explicitly mentioning that these must not be unicode or similar
