Segfault in `pandas.DataFrame.from_records`
The following causes `pandas.DataFrame.from_records` to segfault:

```python
pd.DataFrame.from_records(
    ([(1, 2, 3), (4, 5, 6)],),
    columns=['a', 'b', 'c']
)
```

The above is invalid and should error (a trailing comma led a list to accidentally be a 1-tuple containing a list, which is how I came upon this).
