Review comment:
Frame's `lineno` should always be an integer :
```python
>>> import types
>>> import inspect
>>> types.TracebackType(None, inspect.currentframe(), 3, tb_lineno=None)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: an integer is required (got type NoneType)
```
