It is strongly suggestive that a working prior call to polystr() is no
longer a working call polystr(). Likely reasons might include removal
of the various bits importing pylib/poly.py, removal of the call to
polystr and mucking around in pylib/poly.py that broke things, or some
unforeseen thing that look like them.

Unfortunately, I do not have information to make a diagnosis.
