Okay, basically the answer is that I'm kind of stupid. Months ago, the
users on the wxPython group were discussing this issue and one of them
posted that snippet of code to show how they worked around the issue.
I thought I'd try it and it worked great, although I couldn't really
follow what was happening at the time.

Looking at it now, there doesn't appear to be any reason for the
os.path.join part. I tried running one of my simple scripts with and
without it and they return the same string.

I apologize for propagating erroneous code.
