I'd guess that the sequence in question is the list that's the argument
of join(), in which case item 1 is fn: it should be a string but for some
reason, it is a None value:

,----
| >>> ','.join([str(45), None, "bar", "foo"])
| Traceback (most recent call last):
|   File "<stdin>", line 1, in <module>
| TypeError: sequence item 1: expected string, NoneType found
|>>> ','.join([str(45), "a string", "bar", "foo"])
|'45,a string,bar,foo'
`----
