[Joseph Wang at Labix Tracker]

New submission from Joseph Wang <joe at gnacademy.org>:

smart fails when I run it against my repository

Traceback (most recent call last):#####################################  ( 99%)

    vi = v[i] or None
IndexError: list index out of range

I've fixed this by adding a cache for IndexError

                for i in range(len(n)):
                    try:
                        vi = v[i] or None
                    except TypeError:
                        vi = None
                        pass
                    except IndexError:
                        vi = None
                        continue
                    if vi and vi[:2] == "0:":
                        vi = vi[2:]
