Comment 4 for bug 602825

I've been looking into it, and it appears there are a couple things that might be affecting it (I'm still not sure what is doing it exactly):

From the Python2.7 What's New document (http://docs.python.org/whatsnew/2.7.html):
The copy module’s deepcopy() function will now correctly copy bound instance methods. (http://bugs.python.org/issue1515)

or

http://mail.python.org/pipermail/python-dev/2008-November/083348.html which seems to indicate that copying compiled regular expressions no longer works in 2.5. But, this was not a problem in 2.5, so I don't think this is it.

any other thoughts?
