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

When the application is running, or when it is shutting down?

ValueError: I/O operation on closed file

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(old and probably somewhat outdated, but you get the idea)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