I find similar behavior but it depends on how I initialize the nodelist object. Copied nodelists have the problem but not ones built by parsing code. Here's a trace to illustrate that:

>>> from redbaron import RedBaron
>>> test = RedBaron('#!python')
>>> test[-1].insert_after('# comment')
>>> test[-1].insert_after('# comment')
>>> test
0   #!python
1   # comment
2   # comment

>>> copy = RedBaron('#!python').copy()
>>> copy
0   #!python

>>> copy[-1].insert_after('# comment')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Python/2.7/site-packages/redbaron/base_nodes.py", line 1095, in insert_after
    self.parent.insert(self.index_on_parent + 1 + offset, value)
AttributeError: 'NoneType' object has no attribute 'insert'

So I can insert multiple nodes in sequence, but it seems to depend on how the nodelist was constructed in the first place.

I tried using the patch @andreparames suggested on Dec 10, 2015, but that didn't fix my copied nodelist example.
