I then get the following exception thrown when running my code:

Does anyone have any ideas as to what I’m doing wrong here? Is this a
known issue which has a neat little work around?

Python makes no guarantees that it will tear down your objects before it
tears down the library's objects (or the library itself). See e.g.

http://www.python.org/doc/essays/cleanup/

(old and probably somewhat outdated, but you get the idea)

I'd just put a try/except around it, and ignore any exceptions that may
occur.
