the kind of thing that would do this is:
someobject.some_scalar_attribute = [<some list>]
or:
someobject.some_related_list.append([<some list>])
So your stack trace above would suggest that "author" is a Python list when it
should be a scalar element. Using pdb would help you to drop into a console
at the point the error occurs in which you can inspect "author" as well as
travel up the stack to see where it came from.
