I found a very similar problem with the ingmod package (Python interface to
Ingres DB) on HP-UX 11.

It works fine with Python 2.1 but in 2.2 it breaks the list class's ability
to be used in a for loop (giving the strange error message 'IndexError:
tuple index out of range').

I've not been able to identify where it's failing though :-(
