Are you still using Python 2.1?

In every later version you don't need the
"from __future__ import nested_scopes" line.

So, if you are using Python 2.1 I strongly recommend
upgrading to Python 2.4.1.

I didn't read your code, but this sounds like you have a problem with 
the regular expression engine being recursive in Python versions < 2.4.
Try again using Python 2.4 or later (i.e. Python 2.4.1). The new regular 
expression engine is not recursive anymore.
